Jack’s homework is to make something for the jungle display at school. That evening Jack gets some modeling clay, rolls it into a ball, and—presto!—it's a coconut. Jack thinks he’s finished, but his family wants to help make something more. Dad makes a tree and Grandma knits a vine while Mom makes a snake and little Fred donates a stuffed parrot. Together they make a perfect palm tree. But when Jack gets to school, he finds the pipes have burst right onto the jungle display. What will happen to everyone's work?
