Carle (Little Cloud, 1996, etc.) takes as his premise that animals don't have to go to the gym—their natural movements give them plenty of exercise. "I am a giraffe and I bend my neck. Can you do it?" asks the animal of the child. "I can do it!" is the invariable reply. If readers participate in the gestures shown on every page, they'll get something of a work-out, for the analogies are good: foot-stomping elephants, clapping seals, and shoulder-hunching buffalo are enticingly imitatable. The book's large size and bold, brightly colored animals make it ideal for story hours. Unusual for Carle—and highlighted by the emphasis on action—is the stiffness of the collages: Neither children nor animals convey a sense of motion, but appear locked into place. Linda Lowery's Twist With a Burger, Jitter With a Bug (1995) inspires similar participation, but is a more rhythmic and vivacious book. (Picture book. 4-8)
