My Singing Monsters is a 2012 free-to-play creature-collecting music game for iOS, Android and Steam developed and published by Big Blue Bubble. The player collects and breeds Monsters, each having a unique musical property (some sing, some make drum-like sounds, etc.). There are multiple islands, each with different Monsters, and Monsters that show up on multiple islands have different sounds on each island.

The game's success allowed for its 2014 PlayStation Vita port, as well as the creation of a 2015 prequel called My Singing Monsters: Dawn of Fire, alongside the spinoff games My Mammott and My PomPom, both virtual pet games featuring said Monsters as well as Jammer Splash. A PC port via Steam was released on March 24th, 2021. Also announced is a multiplayer party game, My Singing Monsters Playground and My Singing Monsters: The Board Game, with the former releasing in November 2021, and the latter being a Kickstarter project set to be released in the future.

A live interactive limited series, My Singing Monsters Fandemonium, premiered on March 12th, 2021.

This game provides examples of:

• Absurdly High Level Cap: All over the place.
  • The player caps at Level 100, at which point it will just say "Max". This takes 71,478,403,300 EXP, and is purely for bragging rights as all levels past 41 are Empty Levels that do nothing aside from the occasional Diamond and Relic rewards.
  • Monsters cap at Level 20, which requires millions of food to reach even for Com Mons like Mammott, and the most expensive monster to max out, BeMeebEth, requires 79 million food to max out.
  • This also applies to the Colossingum, but is even worse, as you now need coins to max them out, as well as a large amount of training time. The most expensive monster to max in terms of coins is a Quarrister, at nearly 1 billion coins to get from Level 1 to 20, as well as over 2 months of nonstop training. The monster that takes the longest time to train to max is Fung Pray at over 110 days (nearly 4 months) of training, and also costs over 639 million coins to max. Oh, and you can only train one monster at a time (three if you pay enough diamonds)
  • Monsters on Tribal Island don't have a level cap, with the Tribe level being determined by the combined level of all monsters there. The last level before extras reach Empty Levels territory is 1500, requiring an average of 50 levels for each member, which costs 45,300 shards to reach, per player. Oh, and every week, all monsters in the tribe reset to Level 1, so you have to do it again every week to maximize rewards.
• Added Alliterative Appeal: A number of decoration names are alliterative.
  • To give an example for each letter that has one: Bingo Bango Bongos, Cozee Cabin, Flappy Flag, Glowbe Guise, Harmonorb Holder, Mountain Morsel, Plentiful Planter, Spatial Sapling, and Thumpies Totem.
  • Quite a few Colossingum quests are alliterative: Avian Artists, Backup Buddies, Barbershop Bop, Bat on the 'Bergs, BUM-ble Beginnings, Cool Customers, Dual Duel, Fandemonium Fame, Fandemonium Fun, Fandemonium Fuss, Friday Fracas, Frigil's Feat, From Breeze to Bluster, From Drop to Deluge, From Frond to Forest, Full Foliage, Ghost in the Greenery, Grennitch's Gambit, Hard Rock Heavyweights, Herptile Heroes, Hyddryd's Hurdle, Insect Impresarios, Jaw-Dropping Jam, Jewel amid the Jetsam, Land Lubbers, Mammalian Maestros, Marine Melodists, Monday Matchup, Playful Pioneers, Power Plants, Robot Rock, Saturday Skirmish, Sollum's Stratagem, Sunday Scrimmage, Sustainable Sustenance, Thursday Throwdown, Tuesday Trial, Vegetal Virtuosos, Wasp of the Wasteland, Web We Weave, Wednesday Wrangle, and Zeffree's Zenith.
• Ad Reward: If you can speed it up with diamonds, you can also speed it up with an ad, 15 minutes for each ad watched.
• Alas, Poor Yorick: Roarick’s design, name, and bio reference this, as it sings while holding a skull.
• Ambiguous Robots:
  • Many of the monster species appear to have mechanical transducers embedded into their bodies, such as Phangler's microphone lure, or Deedge and Cranchee's subwoofers. It's never clarified if they are cybernetic enhancements they're simply born with, or organic counterparts that happen to look like them.
  • It can be hard to tell what monsters of the Mech element are mechanical or not. Some are certified Mechanical Lifeforms^note Arackulele, Nitebear, Teeter-Tauter, Auglur, and Vhenshun., others are organic creatures that rely on machines to live^note Reebro, Bellowfish, and Nebulob., wholly organic creatures that simply have natural metal body parts^note Dragong., and a myriad of others that don't represent the element at all. However, Yooreek is the most confounded of the Mech monsters. Although it is artificial by nature, being a lab experiment, it's clearly made of organic flesh. In contrast, the voice coming from both of its mouths is a heavily distorted, bass-boosted vocal synth with audible clipping. Its description acknowledges the discrepancy by putting forth the theory that its robotic voice was "inherited" from the Workshop's previous inhabitants.
  • Wheezel initially appears to be a robotic, one-wheeled jack-in-the-box with autonomously moving parts. Its description refers to it as "some bizarre, sibilating automaton", and its vocalisations are similar to the Yooreek's. Even with the fleshy, cycloptic arm jutting out of its top, one could pass it off as a pure robot with some Organic Technology built into it... until it lifts the lid of its box to reveal a weird mound of organic matter inside of its boxy body, topped with a spittle-producing lip! Furthermore, its "wheel" is actually an ab roller being held by a pair of organic feet. It's entirely possible that this "automaton" is actually an organic creature welded inside of a robotic shell. Given its status as a Living Dream from the neurotic Hyehehe's imagination, the true answer might lead to a myriad of other questions.
• Anti-Climax: In the last part of Spurrit’s verse on Fire Oasis, it holds a "Huz..." for a few moments, looking around, before instead going "Bah!"
• Anti-Frustration Features:
  • After two monsters finish breeding, you have the option to immediately retry the same combination, which is convenient for obtaining rare monsters such as Quad-elements.
  • There's also a rebake option on bakeries, which redoes the last recipe from every bakery on that island, provided you have enough coins.
  • After unlocking Air Island, you unlock the Collect All button, which can be used every 23 hours to collect all coins from every monster on an island, as long as at least one monster is over 75% capacity.^note To make the collect button appear above the monster. Buying any in-app purchase will remove the cooldown permanently.
• Arc Number: Magical Nexus seems to be associated with the number 18, with that being the level you need to unlock it, and also the level the monsters needed to be to travel to it, among other things.
• The Artifact: On Tribal Island, a mysterious monster is encased in amber, being freed once the island’s tribe reaches Tribal Level 100. The island’s bio calls the preserved monster an ancient secret of the Monster World. The monster in question is Kayna, whom, at the time of Tribal Island’s debut, was both a new Monster and the first Fire Monster in the game. Kayna also appears in the prequel game Dawn of Fire, which came out the month after Tribal Island, but it and its fellow Fire Monsters were exclusive to the prequel game for three years, with Tribal Island being the only exception. Since 2018, however, the original game has introduced multiple new islands where Kayna is purchasable and can be bred to produce other Fire Monsters. Tribal Island is still available five levels before any other island where Kayna resides, but if a player hits Level 9 before their tribe hits Level 100, Kayna may already be a familiar sight to them by the time they free it from the amber.
• Battle of the Bands: What the turn-based "combat" of the Colossingum essentially boils down to, with teams of up to three Monsters each, duking it out against other teams of Monsters - using their musical talent.
• Benevolent Monsters: These Monsters are as friendly as they come.
• Bizarre Alien Reproduction:
  • Most Monsters reproduce asexually, according to the description of the Breeding Structure. Apparently they’re more like spores in that regard.
  • When a Cataliszt wants to reproduce, it focuses its dream energy by swatting at the Cradle around its legs. Once it’s accumulated enough energy, it coughs up a hairball spore, which can react with the egg of a Mythical Monster to produce a 'Dreamythical'.
• Bizarro Elements: The game starts out with Plant, Cold, Air, Water, and Earth as the natural elements, with Electricity and Fire in their own categories. From there, we have the Ethereal elements, Plasma, Shadow, Mech, Crystal, and Poison. Mythicals have their own element, alongside the Dream element embodied by Cataliszt and the Dreamythicals. In a similar situation, Legendaries, Dipsters, Titansouls, and Celestials have their own categorical elements, although the Celestials associate with one Natural, Ethereal, or Supernatural element each. The Magical elements include Light, Psychic, Faerie, and Bone. The Seasonals all have their own elements representing their associated seasons, including Spooktacle, Festival of Yay, Season of Love, Eggs-Travaganza, SummerSong, Feast-Ember, and many more. The Primordials share the same elements as the Naturals. And then there are the Paironormals, featuring the most abstract set of Elements yet, with Depths, Control, Hoax, and Ruin.
• Blob Monster: Toe Jammer, the single-element Water Monster, is a blue blob with a face and toes. Other blob monsters include Poppette and Yelmut.
• Blue Means Cold: The color blue is often used in conjunction with the Cold element. Cold Island has a bluish tint and blue ice, the Cold-associated Cool Customers quest awards a blue trophy, and many Cold-element monsters are blue.
• Born as an Adult: In the original game, all monsters emerge from their eggs fully formed, though they start out fairly small and grow larger when fed.
  • Averted in My Singing Monsters: Dawn of Fire, where all monsters are born in their baby forms. However, in this game, only baby monsters can breed.^note According to Parlsona in the original game, monsters reproduce asexually. But it is still weird.
• Boss Battle: Not in the traditional video game sense, but attempting to breed rare monsters could be considered as such, due to them requiring a lot of luck and time to breed and hatch. This is lampshaded in the description of the Boss Monument structure, which consists of all five quad-element monsters depicted together on the structure.
• Boss Rush: Activating a Wubbox requires one of every monster native to the island it's placed on of the same rarity as the Wubbox, including the quads, though it excludes Ethereal^note Except on Ethereal Island., Legendary or Seasonal monsters. This is more apparent on Gold Island, where it needs all 30 natural monsters, including five quads, to activate, not to mention that all 30 of them must be brought to level 15 to get them on Gold Island in the first place, as well as a Wubbox from another island to even begin assembling it.
• Bottomless Pits: Though it's not possible to fall into in-game, the Bottomless Pit decoration is described as having no bottom.
• Bribing Your Way to Victory:
  • You can buy diamonds, which is the currency most monsters require and can also be used to speed up actions such as breeding and baking. However, diamonds just make your game more convenient; it's completely possible to breed every monster in the game for free, although it will take a lot of patience to get certain monsters this way.
  • Not to mention that earning diamonds is actually fairly easy. You have mini-mines that generate 1 a day and every third and tenth day you get diamonds as a daily reward. Finally, some of the tasks can earn you diamonds, such as breeding certain monsters for the first time.
  • Currencies such as keys and relics can also be purchased with real money, but they are easily obtainable from the daily login bonus, and relics can be purchased with diamonds.
• Cactus Person: Barrb fits this trope with its cactus-like body. Epic Flowah also possesses cactus traits.
• Calacas: Clavavera is designed after one if not one outright.
• Cardiovascular Love: Schmoochle, the Seasonal Monster that represents Valentine’s Day, has a large heart on its chest. The Season of Love event itself also incorporates many, many hearts into every part of its aesthetic.
• Christmas Episode: The Festival of Yay event on Cold Island, where players can breed Yool. The Continent from Dawn of Fire also receives Yay decorations at this time, and some Monsters dress up, and as of 2023, you can breed Yool in Dawn of Fire as well.
• Company Cross-References: This game features many references to Big Blue Bubble's previous creations. Thing from Fling a Thing appears inside two decorations where it's encased in (and broken out of) amber, Wickman from Burn the Rope is the critter of Earth Island, and most notably, the two of the titular Thumpies from Thumpies appear as a monster, alongside countless other elements from that game.
• Cross-Referenced Description: Used multiple times in the descriptions of paths:
  • The description of Cold Island's Puddle Path questions the logic of making a path from something so slippery. The Frozen Puddle Path's description is "This must have been thought up by the same genius who created the Icy Path."
  • Multiple of Fire Haven's paths are made of Waxerite. Only the Waxerite Path's description explains what exactly Waxerite is.
  • Amusingly, the descriptions for the Sparkul Path and Glittuh Path on Light Island are very similar, and end with statements of confusion over which path's origin is which.
  • Also on Light Island, the description of the Siennapore Path starts with "Not to be confused with Cyanopores," and vice versa for the Cyanopore Path. The Glowrifice Path's description references both of them.
  • The Ammonaughty Path on Bone Island has a description that mentions the Ammonice Path.
  • On Magical Sanctum, the Rubblerough Path's description states that its stones come from the same quarry as the Teleportal Sigil Path.
• Crystalline Creature: The Monsters of the Crystal element, along with some other monsters such as Tring and Bridg-it, are fully or partially made of crystal.
• Cyclops: One-eyed monsters are an extremely common sight in this game and its prequel. Between regular monsters, Rare forms, Epic forms, and Prismatic forms, nearly every monster is a cyclops in at least one incarnation.
• Dem Bones: Many skeleton-themed monsters: Punkleton ^note A skeleton with a pumpkin head, Clavavera ^note A Dia De Los Muetros-themed skeleton, Cybop ^note Not really a skeleton per se, but contains a skeletal tail, Boodoo ^note A monster who wears a skeletal mask, Bona-Petite ^note A skeletal Wublin with a smaller monster in its ribcage, Loodvigg ^note A Celestial with a skeletal face, and all of the Bone-element Monsters ^note  Clackula, Peckidna, Denchuhs, Hawlo, Withur, Uuduk, Banjaw, Plinkajou, Xyster, Osstax, Roarick, G'day, Larvaluss, Mushaboom, and Enchantling. While they all share the Bone element, only some of them appear to be made of bones, namely those on Bone Island..
• Disc-One Final Boss:
  • Quarrister was originally the final monster to be obtainable upon its debut. However, many more monsters would be released and even an Epic Quarrister is far from the hardest monster to get.
  • Enchantling was supposed to be the last Magical monster released, and the only monster with all four Magical elements, taking 50 hours to breed and incubate. However, the Titansouls were later added that are even harder to get, as they require 10 million coins to buy, require to have awoken all five Colossals and then require you to link other monsters to power them up.
• Disc-One Final Dungeon: Earth Island. It used to be a final dungeon of sorts, being the very last natural island. However, there are many more islands after that, whose Monsters are generally more difficult to breed than those on the Natural islands.
• Early-Installment Weirdness: Some early monsters and islands cover concepts that would be later expanded on with their own elements, such as Fwog representing its Earth element through having gems on its forehead, or the volcanic landscape of Earth Island being made redundant by the Fire element (represented by an anthropomorphic volcano, no less!).
• Earn Your Fun: When it comes to ascending a Celestial Monster on Celestial Island into its adult form, at least one egg of a specific Seasonal Monster must be zapped into its inventory. The catch is that you cannot zap Seasonal eggs from Seasonal Shanty, the only island in the game where you can breed for any Seasonal at any time^note the In-Universe explanation for it is that the power generator within Seasonal Shanty interferes with the ability to zap eggs, thus requiring the player to wait until the specific Seasonal Monster's associated Seasonal event on its associated island and then breed for and zap the egg from there. Though Anti-Frustration Features are also at play here, given that the time window of which you may ascend a young Celestial into Adulthood is also when their required Seasonal Monster and associated Season become active. ^Example Adult Scaratar can only be ascended during August and requires a Boo'qwurm. Boo'qwurm's associated Seasonal event Mindboggle also activated during August. Adult Loodvigg would be considered the exception, but its time window for ascension is during Anniversary Month, which is when every Monster in the game becomes available.
• Duality Motif: The Paironormals, being Monsters that, depending on if they’re on a Mirror Island or not, will either be in a Major^note  if they’re on a normal Island or Minor form^note  if they’re on a Mirror Island .
• Earth Day Episode: Echoes of Eco, an event that occurs on Amber Island and Shugabush Island where Viveine is breedable (on Shugabush Island) or via a Vessel (on Amber Island).
• Easter Bunny: Blabbit. It's a bunny-like Monster with an Easter egg as its shell, and it becomes available around Easter.
• Easter Special: The Eggs-Travaganza event on Water Island, where players can breed Blabbit.
• Eat Dirt, Cheap: Multiple of the food items in Dawn of Fire are made with Stone or Sand.
• Elemental Rock–Paper–Scissors: The battles in the Colossingum have the Monsters use moves that have elements attached to them, which are strong or weak against opposing Monsters based on what elements they have.
  • Musical is a neutral "element" only present in singing moves with no associated strengths or weaknesses. Seasonal elements applied to Seasonal Monsters (Spooktacle, Festival of Yay, Season of Love, Eggs-Travaganza, and SummerSong) similarly lack designated strengths or weaknesses to each other or any other element.
  • Natural Elements:
    • Air moves are strong against Plant Monsters, but weak against Earth Monsters.
    • Plant moves are strong against Water Monsters, but weak against Air Monsters.
    • Water moves are strong against Cold Monsters, but weak against Plant Monsters.
    • Cold moves are strong against Earth Monsters, but weak against Water Monsters.
    • Earth moves are strong against Air Monsters, but weak against Cold Monsters.
  • Ethereal Elements:
    • Plasma moves are strong against Poison Monsters, but weak against Shadow Monsters.
    • Shadow moves are strong against Plasma Monsters, but weak against Mech Monsters.
    • Mech moves are strong against Shadow Monsters, but weak against Crystal Monsters.
    • Crystal moves are strong against Mech Monsters, but weak against Poison Monsters.
    • Poison moves are strong against Crystal Monsters, but weak against Plasma Monsters.
  • If a Monster has multiple elements with contradicting weaknesses or resistances to certain moves (i.e. a Monster with the Plant and Earth elements being attacked by an Air move), the weaknesses will take priority.
• Exposed Animal Belly Button: The following Monsters have visible belly buttons: Drumpler, Potbelly, Entbrat, Blabbit, Gheegur, Floogull, Thrumble, and Plixie. Deedge also has one in the prequel as a Monsterling.
• Expy: Several of the Monsters.
  • Nebulob has what can be described as the singing voice of Elton John during his Tenor Boy years, complete with a detectable British accent.
  • Another Ethereal Monster, Reebro, is essentially a brain on a mechanical platform with mechanical legs, very similar to the Spider Mastermind and the Arachnotron.
  • The Dipsters bear a striking resemblance to Diglett.
  • On a rather meta example, Sooza looks almost identical to the original game's PomPom, but, you know, with a sousaphone.
    • Made even funnier by the fact that the game lampshades this.
    • A similar thing occurs with Xyster and Ghazt, G'joob and G'day, and several other Monster relatives.
  • Yool can classify as an Expy of Santa Claus.
    • Some of Yool's names even reference this: Kris, Kringle, and Santler.
  • Shugabush and its brethren are all Expys of Kristian Bush of Sugarland, being the result of a collaboration between the artist and the game.
• Extra Eyes: Like single-eyed monsters, monsters with three or more eyes are extremely common, especially if Rare, Epic, and Prismatic forms are factored in.
• Extreme Omnivore: The description for the Treecookie Path states that "Monsters can make just about anything work as a snack."
• Fairy Ring: Many monsters of the Faerie element incorporate mushrooms into their design. Squot, Mushaboom, and Cantorell all are examples of this. The latter monster is said to form rings with others of its kind.
• Fan Boy: Cybops are huge fans of Ethereal Island's Jellbilly. So much so that Jellbillies receive fan mail from their Cybop admirers. They do reply to all the fan mail they receive, though.
• Fantastic Flora: The plants and trees of the Monster world are particularly bizarre and fantastical. To give a few examples, the Beeyoot tree poses whenever it's looked at, Fuzzle Trees sometimes steal food from Monsters who picnic beneath it, and Ockulo Trees have eyestalks that stare at Monsters.
• Final Boss: Most classes have a final monster to obtain that's harder than the rest.
  • Mimic is the final natural monster, having all five original elements at once. It requires 500 relics to purchase during the limited time it is available, then takes 80 hours to incubate. This also goes the the Fire Quints on their fire islands.
  • The Epic Wubbox on Gold Island is the hardest Wubbox to activate. It needs almost every Epic Monster on every Natural Island to be fully powered.
  • Amber Island has the Fire Quints again. While they only cost 40 relics this time, they require far more eggs to zap than other monsters on the island.
  • Ethereal Workshop has BeMeebEth, the Quint-Element Ethereal (known in its bio as the Top Boss of the Workshop). To synthesize BeMeebEth, you must use a Quad-Element Ethereal, plus three Meebs attuned to each of the Quad's Elements and four Meebs attuned to BeMeebEth's fifth Element, with a low chance of success. And it takes a whopping 55 hours to synthesize.
  • The Magical Islands have the Titansouls, who require all of the Colossal Conundrums to be completed, cost 10 million coins each and require 12 monsters to be linked (4 Common, 4 Rare and 4 Epic), which uses tons of Coins and Diamonds unless you're happy with only linking one monster per day. However, the Titansoul will still provide currencies and sing without having all 12 linked.
• Freemium: The game can be played entirely for free, but microtransactions are present. Buying any resource pack (food, coins, diamonds) with real money will make premium structures available. It will also remove the in-game advertisements.
• Friend to All Living Things: Viveine likes to befriend the critters that dwell on the island, especially the Wingalings.
• Genius Loci: Nearly all of the islands are actually Colossals or Titans, giant and ancient beings. Zooming out on most islands allows the player to see that the Monsters are really singing atop a giant monstrous head, complete with a face and often horns.
• Gentle Giant: This trope is named-dropped in Entbrat's description.
• Good Wings, Evil Wings: Zigzagged. Friendly-looking Monsters like Tweedle and Schmoochle have avian wings, while the grumpy-looking Grumpyre has bat wings. However, Grumpyre is said to look much grumpier than it actually is, and several perfectly nice Monsters, like Floot Fly and Riff, also have bat wings.
• Goo It Up: Along with ghosts and spirits, Plasma Monsters tend to incorporate slime into their designs and concepts.
• Green Hill Zone: Plant Island is the island you start the game on, and is themed after a lush, verdant plain.
• Halloween Episode: The Spooktacle event on Plant Island, where players can breed Punkleton.
• Home Base: "Seasonal Shanty" is a wooden structure stuffed with Seasonal decorations floating along the Living Ocean, that only Seasonal Monsters know how to find. Seasonal Monsters go to Seasonal Shanty to rest and relax when their respective events aren’t running, or in the case of the migratory Schmoochle and Yool, just want a familiar place to kick back and relax in. It’s also noted that all Seasonals drop by during Anniversary Month to join in the celebrations.
• Hot Skitty-on-Wailord Action: You can breed almost any combination of Monsters (except for two of the same Monster), which leads to some interesting matchups. It's downplayed due to the fact that Monsters seem to reproduce without directly mating.
• An Ice Person: The Monsters of the Cold element are linked to ice and snow.
• Insistent Terminology: Implied in the description of the 'Cold Globe' decoration, "It's not like the element is called Snow, it's called Cold. We're very insistent about it at this point."
• Instant Awesome: Just Add Mecha!: Joining the cast of run-of-the-mill Monsters, we have Wubbox alongside its Rare and Epic counterparts; giant dancing robots that contribute dubstep to the islands they are on.
• An Interior Designer Is You: Most islands are able to be decorated to your liking (though Monster preferences may influence how you position the decorations).
• Interspecies Romance: Any breeding pair, since you can't breed two of the same Monster together.
• Item Crafting: Dawn of Fire supplants the simple food system from the main game with a more elaborate crafting system, where items are either used to level up Monsters or upgrade structures. The simplest items can be obtained by producing them from structures or obtaining them from the Wondermine (or collecting them around the Continent, in the case of crystals and Seasonal Cheer). These items can then be placed into specialized crafting structures (ex. Bakery, Jeweler) to create new items. The newly-crafted items may also be used to craft even more complex items, which tend to have longer production times than more basic items, but provide greater boosts to Monsters' levels (or are used for later-game upgrades).
• Lethal Lava Land: Earth Island, the final natural island, is an area of cracked magma.
• Levitating Lotus Position: This is the position that Flum Ox takes, though its arms are actually mobile horns.
• Level Editor: The Composer Island allows you to make your own songs using the Natural monsters. The My Singing Monsters Composer app, which is a separate app, is essentially an improved version where you can use the Single and Double Elemental Ethereal, Seasonal, and some Rare Monsters.
• License-Added Game: In 2013, a spinoff game staring The Muppets called "My Muppets Show" was released. It featured the same gameplay mechanics as My Singing Monsters, having five stages and a variety of Muppets to collect. The game was shut down in early 2015.
• Living Dream: The "Dreamythicals" are Mythical Monsters dreamed into existence by other Mythicals, with help from a Catalizst. Each Dreamythical reflects the Monster who dreamed it up in some way.
• Multiple Head Case: Not an uncommon sight among the game’s titular Monsters. Examples include Potbelly, Quibble, Quarrister, Smoochle, Cantorell, Gaddzooks, Whaill, and Rare Dandidoo.
• Musical Anatomy: A large assortment of Monsters play parts of their own bodies as instruments.
• Never Say "Die": ZigZagged. The only mention of death is in Clavavera's bio, which mentions monsters passing on to the Beat Hereafter. Additionally, the Vessels on Amber Island are pretty much urns or canopic jars, although the amber eggs they bear can be rejuvenated and hatched into living Monsters.
• Never Trust a Title: The "My" part only affects the gameplay, with the trailers and Handler Shorts having the monsters not being owned by anyone. Less than half of all of the monsters sing throughout the entire game, despite the "Singing" in the title, as other monsters play instruments and don't sing at all.
• No Celebrities Were Harmed: Shugabush is based in appearance on vocalist Kristian Bush of the American country music duo Sugarland, including his beard and mandolin. Its name is a portmanteau of Sugarland and Bush's last name. As noted in Real Life Writes the Plot, this is a unique use of this trope in that Kristian Bush himself collaborated with Big Blue Bubble to create Shugabush. Shugabush even has other related Monsters on their own island, which plays a variation of Kristian Bush's song "Love or Money".
• Non-Malicious Monster: The Monsters can't really be classified as mons as they're not summoned and certainly not for fighting purposes, they're friendly or non-malicious. While some Monsters like Punkleton, Grumpyre, or any other Shadow-elemental can look a bit 'dark' and T-Rox might appear dangerous, none of the monsters are harmful or violent even if a few of them might be a bit neurotic. They just want to sing and dance for money, look at interesting decorations, eat what you bake them, and pal around with the monsters they're chummy with.
• Occult Blue Eyes: Enchantling’s eyes are bright blue, signifying its great power as a quad-element pure Magical monster.
• Odd Friendship: The friendship between Hyehehe and Cherubble. Unsurprisingly, as the creators of Cherubble and Hyehehe are friends in real life.
• Our Dragons Are Different: Dragong, Furnoss, and Carillong are all designed after eastern dragons. The adult Glubber may count as well, resembling a Panlong.
• Our Fairies Are Different: Faerie is one of the four Magical elements, corresponding to Faerie Island. The Faerie element encompasses a variety of monsters with differing designs, though mushrooms seem to be a common theme. A few non-Faerie monsters also incorporate elements of fairies in their designs, such as Plixie, a fluttering Celestial monster that represents the Plasma element.
• Our Monsters Are Different: These ones can sing and dance.
• Our Monsters Are Weird: Weirdness is in no short supply among the monsters of My Singing Monsters, due in no small part to the fact that they produce music with their bodies. Many percussionists use their hard heads, bellies, or pincers to keep the beat. Woodwind and brass monsters that don’t play a physical instrument typically play their sounds through holes in their bodies, with some having recorders sprouting from their backs, flutes for noses, or didgeridoos for tusks. String instrument monsters can draw sound from their arms, tongue, hair, or ocular nerves. Of course, vocalists are in no way exempt from weirdness. Among their kind are a Blob Monster with lots of toes, an eyeless blob that sees with its tongue, a Cyclops jellyfish with a moustache, an anglerfish with two microphones for lures, a one-footed yodelling Mouthy Bird, and a four-eyed pile of mulch. Alongside this, the game makes frequent use of monstrous design tropes. Cyclops, Armless Biped, Cephalothorax, Extra Eyes, Vertebrate with Extra Limbs, and Multiple Head Case are fairly common sights in the monster world.
• Overhead Interaction Indicator: Appears whenever a monster makes a significant amount of currency, breeding/hatching is done, dormant Wublins and Celestials’ revival time limit expiring, etc...
• "Pachelbel's Canon" Progression: Gold Island's song uses a chord progression that is similar to the canon.
• Palette Swap: Rare and Epic Monsters produce the same music as their Common counterparts, but are rarer and have alternate designs, with Epic Monsters changing more drastically and having unique animations in the case of Seasonal and Mythical Monsters.
• Pattern-Coded Eggs: Exaggerated in that the eggs not only have the colors, but textures of their respective monsters!
• Plant Person: The game contains a multitude of humanoid monsters with the Plant element. Examples include Shrubb, a scrawny beatboxing shrub person; Entbrat, a giant with wooden antlers; Flowah, a muscular sunflower who sings in tribal chants; and Barrb, a Cactus Person.
• Play Every Day:
  • The main game offers a daily bonus for those who check in every day, via a 10-day cycle (A number of coins on day 1, then 25 diamonds on day 10; the cycle repeats, and on day 11 the player receives coins again and so forth).
  • Dawn of Fire has a daily dice-rolling game used to obtain Celestials: roll three dice, and you'll get a combination of coins, diamonds, and steps, the latter of which are used to progress through the Celestial's constellation until the point where you unlock the Monster. The game encourages you to login every day, as if you have a daily streak of 4 dice rolls, you gain a bonus dice, meaning greater rewards, and a greater chance of obtaining the Celestial before the month's end.
• Playing Card Motifs: Hyehehe has a spade and diamond on its patchy skin, while Wheezel (the Dreamythical Hyehehe created) has the hearts and clubs.
• Pocket Dimension: The Monster World has a pocket dimension that actually predates the main dimension, and was used by the Colossals as their experimental sandbox to practice the Spark of Life. Currently, the Ethereal Colossal Zarroë serves as the foundation of Ethereal Island in the pocket dimension, where it houses the Ethereal monsters on top of its head (and in its brain, and on its hand). The only other inhabitants of the pocket dimension are Enchantler, a morose Titan that founded Magical Sanctum in the middle of an alien forest, and the Magicals that it supports.
• Poisonous Person: The Ethereal Monsters of the Poison element, with Humbug as their single-element representative and Oogiddy as the quad of the bunch.
• Progressive Instrumentation: Because each monster adds one instrument or vocal part to an island’s song, every island is this trope.
• Pseudo-Santa: In the Monster world, Yool is the Santa Claus figure for the Christmas-equivalent Festival of Yay.
• Rewards Pass: The Clubbox, to an extent. You can get rewards such as decorations, costumes for monsters as well as hard to get monsters by generating Hype gained after partaking in side-quests. Fortunately, there isn't a paid section.
• Rock Monster: The Earth element contains a number of monsters made of rock and stone, including Noggin, T-Rox, and Quarrister.
• Samurai: The Mythical Monster Strombonin is based on a samurai, and it plays a conch shell horn much like the horagai some samurai would play to send signals to their armies in battle (though in this case, the shell still houses a living mollusk, and the sound comes from that mollusk’s cries).
• Scary Jack-in-the-Box: Wheezel resembles a jack-in-the-box, and it’s quite scary, even compared to other monsters. If the creepy eye-hand isn’t enough to frighten you, you’ll likely jump when it reveals its fleshy mouth.
• Series Mascot: Mammott is prominently used to promote the main games. They even have their own spin-off virtual pet app, My Mammott as well as plush toys of them among other merchandise.
  • Furcorn also serves as the series mascot, being on the app icon of the first My Singing Monsters game, and having its own plush toy as well as other merchandise.
• Smelly Skunk: Epic Boskus is described as smelling foul and has skunk-like black and white fur.
• Sorting Algorithm of Threatening Geography: Sort of. The first island can be classified as Green Hill Zone. The next 3 islands are in a freezing environment, high up in the sky, and underwater. Then, the final main island is a Lethal Lava Land, though no danger is posed as the monsters just sing and dance without anything bad happening to them. The islands that come afterwards generally get more abstract and surreal.
• Speaking Simlish: A majority of the monsters that vocalize do so in gibberish. PomPom, Congle (on Tribal Island), Shugabush, Hoola, Rare Wubbox, Blipsqueak, the Werdos, T-Pirainha and BeMeebEth avert this, using actual words when they vocalize.
  • In the prequel game, Kayna and Furcorn sing English words on Party Island, as do PomPom and Cybop on the Continent.
• Spirit of Halloween: Punkleton is the representative for the Halloween-equivalent Spooktacle.
• St. Patrick's Day Episode: Cloverspell, a seasonal event that takes place on Faerie Island in March. The seasonal monster Ffidyll is obtainable during this event.
• Unexpected Gameplay Change: The Colossingum takes the game from something you sit back and relax to, and turns it into a turn-based combat mini-game, where you train monsters to sing against other monsters to unlock music tracks for the island, as well as costumes for the monsters to wear.
• Valentine's Day Episodes: The Season of Love event on Air Island, where players can breed Schmoochle and one Rare and Epic a day.
• The Very Definitely Final Dungeon: Not in the traditional sense, but Gold Island serves as the "final" place for your monsters to stay if you choose to. Celestial Island could also apply, in that the monsters there are some of the most difficult to obtain.
• Weird World, Weird Food: A lot of Monster world food looks similar to food we know, but there are a number of key differences. Among standard Treats, the Ice Cream and Cake are topped with eyeballs, the Turkey has oddly placed and extra limbs, and the Big Salad contains purple tentacles. Dawn of Fire contains a greater variety of food items, some even odder: Coconut Cheese, String Noodles made from Grain and Rope, Rock Candy made with real Stone, and numerous foods made with Sand.
• Whale Egg: Every monster hatches from eggs, whether they are based on birds, reptiles, non-monotreme mammals, or even robots.
• White Bunny: The Cold Island critter resembles a white rabbit.
• Wingdinglish: Written text on some items is in Monstrous, an alphabet that can be translated to English.
• With Lyrics:
  • The Werdos add lyrics to the songs of the five Natural Islands and Fire Haven.
  • BeMeebEth adds lyrics to Ethereal Workshop, though it's a downplayed case due to it being only true for two verses of the song.
• The X of Y: A number of decorations have names of this structure: Hut of a Thousand Perfumes, Orb of Alkino, Pipes of Cicado, Pot of Enchanted Coins, and Spirit of Creation.
• You Mean "Xmas": The monster world has its own versions of well-known holidays. (Lunar) New Year is Crescendo Moon, Valentine's Day is the Season of Love, St. Patrick's Day is Cloverspell, Easter is Eggs-Travaganza, Earth Day/Arbour Day is Echoes of Eco, International Museum Day is Perplexplore, Pride Month is Sky-Painting, Halloween is Spooktacle, Día de los Muertos is the Beat Hereafter, Thanksgiving is Feast-Ember, and Christmas is the Festival of Yay. There's also SummerSong and MindBoggle, although they're respectively tied to the Summer and Back to School seasons as a whole rather than any one holiday, alongside Life-Formula and Anniversary Month, which are events associated with anniversaries specific to My Singing Monsters (namely the release of Ethereal Monsters and the game as a whole respectively) rather than Real Life holidays.
