Piper and Clancy have a snow day from school, but instead of a day of snowy fun outdoors, they must stay indoors due to the wind and cold temperatures. They quickly get tired of their usual games and books, and they moan that they don't have anything to do. But then, the willow tree invites them to the barren Penguin Island off the coast of Namibia, and they learn from a group of penguins that one can have fun even when you are surrounded with what looks like nothing.
