"Hey everybody! Come move your feet!" " "Says Tommy T-Rex. "I'll give you the beat!" " "Tommy's claws clap-clap, his feet tap-tap, " "And his T-Rex jaws go SNAP! SNAP! SNAP! " This sturdy board book introduces little ones to an unusual animal in snappy style--literally. This simple short tale tells how Tommy T-Rex sets the beat for an earth shaking dino dance-athon. And all the while, children can SNAP-SNAP along with the animal's jaw, which forms the "top" of each book.
