The elephant thunders out his boast—``No one can bring me down!''—and the monkey's talking drum sends the challenge echoing across the plains. The leopard, the crocodile, even the rhinoceros are easily vanquished, but not the little bat: she bites the elephant's ear until he drops to the ground to rub it. Sierra's retelling of this folktale collected in Cameroon is suitably vigorous; in Pinkney's swirling scratchboard illustrations, the animals (except, of course, the bat) are huge, gnarled, and solid. Colorful and dramatic. (Folklore/Picture book. 6-8)
