The Time of Great Giving has arrived, and everyone in the Great Valley is excited about the big feast. Everyone, that is, except Chomper. It's pretty lonely being the only sharptooth at a leaf-eater feast. So Chomper decides to go out into the Mysterious Beyond and try to teach the sharpteeth how to be friends. But the sharpteeth Chomper meets aren't very friendly!

When Cera accidentally scares off some bellydraggers, everyone thinks that she's rid the Great Valley of them and she's a hero. Pretty soon, Cera believes it, too! Cera becomes very proud of her made-up accomplishment. That is, until everyone discovers the bellydraggers are still in the Great Valley!
