The first sixteen pages contain various prompts regarding defecation in animals such as opposites ("An elephant makes a big poop" and "[a] mouse makes a tiny poop"), comparisons (that various species produce various sizes and shapes of poop) and questions ("What does whale poop look like?" and "Which end is the snake's behind?"). On the seventeenth page, a boy with black
overalls and a red shirt is introduced, seen running into a bathroom. The book then goes on to explain how people of all ages, from adults to very young children, defecate, and how
infants may use
diapers. After that, there are only three more pages that do not feature the boy with those pages featuring rhinos, cats, pangolins, water buffaloes and alligators. On the next page of the book, the child uses
toilet paper and flushes the toilet. The final portion of the book explains that because every animal eats, they must therefore defecate, and the book ends with rear views of the boy, a pig, a pelican, a zebra, a gorilla, a lion and a giraffe defecating and the words "Everyone Poops". ==Publication==
