Illus. in full color. "Only Burningham could make an ecological fable so much fun. A boy goes to bed and dreams that he and his stuffed dog, now a railroad engineer, are speeding through the countryside playing games and picking up endangered animals. Spacious drawings contrasted with textured landscape paintings create a striking effect as the artist juggles antic humor with a serious message--and never misses a beat."-- "Bulletin, Center for Children's Books.
