Mungo the Elephant and Mr. Thunderpants love playing jokes on each other, but they really love playing jokes on their friends. They hide clockwork chattering teeth in Dawg’s pants, put a whoopee cushion in Davey Duck’s nest, paint glasses and a moustache on Mrs. Moody while she is napping, and sprinkle sneezing powder in Mr. Legg’s hat — all with hilarious results. But the duo’s friends don’t find their jokes to be so funny and hatch a plan to teach Mungo and Mr. Thunderpants a lesson. With bold images and simple text, this engaging book teaches children the appropriateness of practical jokes in an enjoyable way.
