From Publishers Weekly:
Starred Review. "Shea (New Socks) makes a hilarious commentator as his hero, a small red dinosaur, elevates everyday encounters into a series of matches worthy of the WWF. Again and again, Dinosaur proves unbeatable.... Incorporating paper, paint, photo collage and quick strokes of crayon, Shea's freewheeling compositions convey both a beguiling spontaneity and a preschooler's sense of invincibility. Kids will be only too happy to capitulate to this irresistible package."

From School Library Journal:
"Illustrations with strong lines and bright colors keep the energy high without being cluttered. The predictable text and lively expressions of this cartoonlike character will appeal to kids who are on the go all day. Just don't expect them to go down quietly as they will be roaring right along with this little hero."
