From Todd Doodler, the creator of BEAR IN UNDERWEAR!, comes a silly story about a polite, well-behaved Tyrannosaurus Rex who discovers that being a dinosaur is tough work. Rex is bigger than all the other kids in class. He's bigger than his teachers! His gym clothes don't fit. His desk is too small. And he is horrible at playing hide-and-seek. But worst of all, everyone thinks he's super scary! But that doesn't get Rex down! Instead he teaches everyone exactly why being different is great in this hilariously heartwarming story about making friends, getting along, and learning to say RAWR!
