The 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.
Mother sees a new hat at the shops, but it is bought by another penguin. She settles for another hat, only for Pingu and Pinga to ruin it by playing too roughly. The young penguins secretly patch it up so that it's as good as new, and in fact it now looks more like the hat that Mother really wanted.
