Knock! Knock! Who's There?

Knock, knock . . . who's in there? A hilarious group of animals, all going potty, teach toddlers a fun lesson in bathroom etiquette. As kids open the doors, each creature demonstrates how to behave properly, from flushing the toilet, to washing your hands, to turning off the light before you leave. This humorous, silly story helps children with toilet training . . . and more.
