William the guinea pig is sure that life is more fun outside his hutch. He sees the squirrels running and chattering in the yard and longs to join them. So when a squirrel named Stella drops out of a nut tree, offering adventure, William is happy to leave his little hutch behind. But he soon discovers that guinea pigs aren't so well suited to life in the woods— and that squirrels don't make the most reliable friends. Luckily, restless little William has a very resourceful mother.
