Mac makes a home movie about Foster's for his school project, but Bloo edits it into a humorous film with flatulent sound effects, which leads him to be entered in the state student film festival. With Bloo's help, they make "T-Rexatron Alienwolf III, A Prequel In Time: The Unrelenting."

Tropes in this episode:

• 2D Visuals, 3D Effects: Spoofed with the CGI Eduardo in Bloo's movie.
• Actor Allusion: The movie scene where Wilt's character travels through a time portal pays homage to Samurai Jack. Fitting as Phil LaMarr voices both Wilt and Samurai Jack.
• Amateur Film-Making Plot: The school principal is impressed with Mac's film about Foster's (which Bloo added armpit fart sound effects into) and enters Mac to represent his school in the Annual State-wide Elementary School film festival. He gives Mac a $500 budget and the idea for the film, which Bloo helps make into a movie called "T-Rex-A-Tron Alien Wolf III: A Prequel In Time: The Unrelenting". Despite all the extra effort and money Bloo puts into the film^note which includes having Tom Hanks play a robot and a CGI Eduardo when the real one refused to be involved with the project, which Mac had to pay for by selling his Space Wars action figure collection and Madame Foster's antiques (which she unknowingly bought back anyway), the ending to Bloo's movie gets taped over by an episode of Lauren is Explorin' that Eduardo was trying to watch but taped over the master, causing Bloo's film to lose.
• Bad "Bad Acting": Mac's raw home movie is full of this.
• Bait-and-Switch:
  • When Mac is waiting at the principal's office, both him and the audience thinks Bloo's cut of his home movie got him in trouble... but surprisingly, the school principal actually liked Bloo's cut and thinking it was Mac choosed him to be the representative for the school at the Annual Statewide Elementary School Film Festival.
  • After filming a scene where Coco has to disarm a bomb while suffering from a fatal disease, Bloo says "I smell Oscar!" The camera then zooms out, revealing a big, green imaginary friend named Oscar to be standing next to Bloo.
• Big "WHAT?!": Mac says one in response to Bloo having Tom Hanks in the movie and needing $3 million to pay him.
• Booing Crowd: At the film festival, most of the film has very little to do with the topic of friendship, and Eduardo's show taped over the ending causes Mac to lose the contest.
• Budget-Busting Element: In-Universe. Mac is tasked with creating a movie to be shown at a film festival, with Bloo directing. Bloo immediately blows their budget a megaphone (said to have once belonged to Cecil B. DeMille) to boss everyone around with, leaving Mac to sell some of his stuff online to scrounge up more money.
• Creator Cameo: Craig McCracken voices a fictionalized version of himself.
• Colon Cancer: Parodied, with Bloo's movie being called "Trexatron Alienwolf III: A Prequel In Time: The Unrelenting".
• The Greys: The imaginary friend in the dance scene handcuffed to Wilt looks like one of these, with the only major differences being that's he's only slightly shorter than Wilt and has white eyes with slit pupils.
• In a World…: Parodied; this is how Bloo starts the movie he made for Mac's school's film festival
  Bloo: (Voiceover) In a world where chaos reigns like cats and dogs in a hailstorm...
• Invisible Celebrity Guest: Bloo brings in Tom Hanks for a cameo in the movie to play a robot, but he appears with a bucket on his head and his lines unintelligible.
• Jerkass Has a Point: Bloo had a point to call Mac out for having a lack of faith in Bloo's cut of the home movie, especially since Mac jumped quick to conclusions that the new cut got him in trouble without the full details.
• Literal-Minded: The principal states that the movie needs to be themed around friendship. So Bloo literally includes a sea vessel called the 'Friend Ship' into the movie's plot as a means of Loophole Abuse.
• Megaphone Gag: When Mac and Bloo attempt to film an entry to a film festival, Bloo turns into a Prima Donna Director who alienates the entire crew by constantly barking orders at them through a megaphone, which he shoves in their faces. It gets even more wasteful when Bloo spends the entire budget for the movie on purchasing the megaphone.
• Mistaken for Flatulence: Mac films a video about the imaginary friends who live at Foster's, which Bloo adds armpit fart sound effects to, specifically during the scene where Mac interviews Eduardo. This causes Eduardo to think he has a "Pooting problem", despite Mac trying to tell Eduardo otherwise. This is why Eduardo refuses to take part in the movie Bloo films for the film festival Mac's principal enters Mac in, and Bloo has to replace him with CGI effects. Eduardo also sends a letter to the writers of Lauren is Explorin' for a solution to this problem, prompting them to write A Very Special Episode dealing with it.
• Musical Pastiche: The dance scene of the movie features a parody of All Star. The lyrics even reference ogres, as a Shout-Out to the Shrek series given the song's memetic origins.
  Wilt: Hey Now, Yeah Yeah, Hey Hey Yeah...
  Hey Now, Yeah Yeah, Shine a Ray...
  Robot Robot Vampire, Ogre Ogre Robot!
• No Ending: Mac laments to an upset Bloo about them losing the film festival that even if all but the beginning of the movie hadn't been taped over by Eduardo, the movie still had no ending. Bloo counters that as long as everything else was awesome, they didn't need an end- cue "The End" card.
• Not So Above It All: Mr. Herriman joins the others laughing as they watch Bloo's "improvements" of Mac's home movie—the "improvements" being Bloo adding farting sound effects every ten seconds, something you wouldn't expect someone like Herriman to find humor in.
• Orbital Shot: Attempted by Bloo during the filming of T-Rexatron Alien Wolf III, specifically during the scene where Coco hands Wilt a tuna fish sandwich. The camera itself was an imaginary friend who said he always hated that effect.
• Prima Donna Director: Bloo turns into one of these when he is partnered with Mac to produce a film for the film festival. He constantly orders Mac around and spends their entire assigned budget on a megaphone.
• Real Trailer, Fake Movie: To Bloo's movie.
• "The Reason You Suck" Speech: When waiting outside the principal's office, Mac gives Bloo a mini speech:
  Mac: Bloo, you've done some terrible things, but this is the worst. Do me a favor. Next time I ask for help, just butt out. All you do is get me in trouble...
• Spotlight-Stealing Title: In-Universe. Mac is credited for the creation of the movie and given top billing but only in the form of a small, simple, monochrome title card. Bloo on the other hand is given a dramatic, elaborate and animated sequence for his role as executive assistant.
• "Shaggy Dog" Story: Despite all the hard work everyone went through for the insanely expensive movie - mostly Mac as he had to get the funds for the movie after Bloo made it go overbudget - they end up losing thanks to Eduardo taping over the master copy.
• The Stinger: The end credits scene has the gang watch Lauren is Explorin' with Eduardo, when Ed suddenly farts and says, "Excuse me", making everyone else grossed out.
• Vampire Dance: Wilt and the grey alien in the dance scene do a dance move called Vampire.
