A.J. and his friends are in for a wild adventure when their school bus gets a flat tire and their driver, Mrs. Kormel, gets lost in the middle of nowhere.

When a bus driver takes a break from his route, a very unlikely volunteer springs up to take his place -- a pigeon! But you've never met one like this before. Narrated by Mo Willems and Jon Scieszka with animation by Pete List.

Taking the bus to make a delivery to his grandmother, a little boy is alarmed by the bus's scary driver, who grows creepier by the minute as the other passengers disembark.
