You poop here! In a potty, of course! Fun pictures of animals — an ant, an alligator, a bat, and more — make this a perfect potty training book — and more! It’s especially appropriate for inquisitive, science-minded toddlers and preschoolers who are curious about how their bodies work.

With an author’s note about What is poop? and fun facts about the animals featured in this book. (From GoodReads.)
