The Pigs go out into the yard on a snowy day, and the children build a snowman. Peppa thinks the snowman needs a house, but Daddy Pig points out that there's no bricks. However, he then brings out buckets and spades, and the Pigs make bricks out of snow. Then, they explain that they'll make an igloo, which is a house made of snow.
The Pigs make the igloo, and Daddy Pig gets sealed inside and leaves by making a door. The Pigs sit inside the igloo, which Mummy Pig finds too dark, so Daddy Pig uses some ice from a bucket to make a window. The Pigs sit in the igloo to keep warm, but Peppa points out that the snowman is outside. Mummy Pig points out that snowmen are supposed to be cold.
Then, the Polar Bears show up, enjoying the snow.
