Hillenbrand takes license with the familiar song (the traditional words and music are reproduced at the end) to tell an enchanting story about baby animals picked up by the train and delivered to the children’s zoo. The full-color drawings are transportingly jolly, while the catchy refrain—“See the engine driver pull his little lever”—is certain to delight readers. Once the baby elephant, flamingo, panda, tiger, seal, and kangaroo are taken to the zoo by the train, the children—representing various ethnic backgrounds, and showing one small girl in a wheelchair—arrive. This is a happy book, filled with childhood exuberance. (Picture book. 3-6)
