Plot

The book is designed to help toddlers identify wild animals (from the zoo) and the noises they make. It features a polar bear, a lion, a hippopotamus, a flamingo, a zebra, a boa constrictor, an elephant, a leopard, a peacock, a walrus, a zoo keeper and some children. This is a companion book to Brown Bear, Brown Bear, What Do You See?, published by Carle and Martin in 1967, replacing the earlier text's colours and common animals with sounds and less common animals.
