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. When Pingu's grandfather tells him all about the moon, Pingu desperately wants to visit. With Pinga's help, Pingu makes a rocket out of an old barrel, some tin foil and snow. When they pretend that the rocket has landed on the moon, they are shocked to see an alien face at the window, until they realise it is only Grandfather joining in.
