The only thing bigger than Lionel the rhinoceros is his enthusiasm to join in!

Lionel loves to join in with whatever his friends are doing - playing cars, making music or baking! But his enthusiasm means he usually leaps before he looks, leading to disaster. Finally Lionel seeks out some quiet space. As he relaxes Lionel has a great idea, and this time it's his friends who ask to join in... all aboard the world's greatest rhinocer-raft!
