Written from the perspective of an eager and curious toddler (and, unlike other potty-training books, designed to teach both boys and girls), this charmingly illustrated book celebrates every successful trip to the bathroom with a “potty palooza” and stars an endearing and quirky cast of characters: potty hippos, who gather when you use too much toilet paper; space aliens, who zoom in to try to use your potty; a wild elephant; and the Poop Police, who issue Mom or Dad a ticket for sounding too silly when singing the “Potty Song.”
