"Shake, shake, shudder . . . near the sludgy old swamp. The dinosaurs are coming. Get ready to romp." A neon-bright Brontosaurus, a dancing Deinosuchus, and other raucous dinos gather at the swamp for a wild, earth-pounding party in this exuberant picture book. Mitton's gleeful rhymes introduce dinosaur species as they rumble and boogie across the spreads in irresistible, color-saturated cartoonlike artwork that shows the humor and farce of the giant beasts shaking their scales and tails. The book ends with a nighttime scene of sleeping dinosaurs that's perfect for bedtime reading.
