There is a mean, violent tyrannosaur on land, and everyone hates him. One day, a cliff falls apart, and the tyrannosaur falls down into the ocean. An elasmosaurus, who lives in the ocean, helps him, and the tyrannosaur says “thank you” for the first time in his life. They become friends, and the elasmosaurus thinks the tyrannosaur is very kind. When the elasmosaurus asks if the tyrannosaur knows about the violent dinosaur on land, he can’t tell the elasmosaurus the truth. With vivid illustrations, the book delivers a moving story of friendship.
