Walking home from school, Thomas, a little boy, is thinking about how nice it would be to be a teacher. Out of the bushes comes a tiger who confesses to Thomas that he ran away from school because he thought he was too dumb to learn. Thomas not only teaches him to tip-toe and tetter, but soon has to teach a hippo and a giraffe to hop and hobble and juggle and jiggle. People notice their actions and love their performance. Can Thomas teach them more tricks?
