Aiden tries to make friends with kids who love different animals--a slow-and-steady Turtle builder, a fast-running Dolphin, a high-climbing Goat, and a shy Bunny--but no one seems to want to play exactly the way Aiden wants. Will Aiden ever find a friend who fits his idea of "best"? Or will his older sister, Maya, help him realize that the perfect best friend is simply someone who is happy to play with you, differences and all?
