Did you ever wonder who rides the zoo train early in the morning? Climb aboard and join the mischievous, sleepy, and playful baby animals on their way to the children's zoo. The engineer has to get them there before the first busload of children arrives - but these baby animals just want to have fun! This delightful adventure full of mishaps, daring rescues, and a runaway red balloon has a cumulative text and playful animal noises that will have readers singing along-if they are not racing to the zoo to ride the train themselves. In this version of a familiar song, baby animals ride to the children's zoo on the zoo train. Printed music on last page. Join Will Hillenbrand's group of mischievous, playful, and sleepy baby animals on their way to the children's zoo. You'd better hurry, though - they can't be late to greet the first busload of children!
