Animated adventures of Pingu, the clumsy young penguin who is always up to mischief in his snowy world. His companions are his baby sister Pinga, his best friend Robby the Seal, his caring mother and his father, who is the local postman. Penguins come from all over to buy snacks at a new snack stall, and Pingu is first in the queue. He casually drops the wrapper when he has eaten his treat, and everyone else copies him. Soon, the Antarctic is covered in wrappers. Pingu realises that he is to blame, and leads a mass tidy-up.
