Book excerpt: How do you find a missing dinosaur who’s large and green and likes to roar? When a little boy’s dinosaur decides to play hide-and-seek, he is surprisingly difficult to track down. Veteran illustrator Joe Mathieu’s dinomite illustrations and Jon Surgal’ s saur-ing verse will have kids roaring with laughter as they romp through this funny rhyming Beginner Book. Originally created by Dr. Seuss, Beginner Books encourage children to read all by themselves, with simple words and illustrations that give clues to their meaning.
