Pre-school stop-frame animation. 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. Pingu discovers that the further he rolls his snowballs, the bigger they become. Together, he and Pingo roll an enormous snowball up a hill. But the snowball rolls back down the hill and towards Father's snowcart, taking washing lines, rubbish bins and Pingo with it. Pingu must race the snowball to warn penguins in its path and to save all the parcels loaded up on the snowcart.
