A young boy takes a new book into the bathroom to read. But what a strange story! One by one, all sorts of animals—a cow, a polar bear, a lion, and more—race across the pages. But where are they running to? Then, the boy’s reading is interrupted by a loud knock on the bathroom door. The very same creatures are outside, lined up to use the toilet! This story within a story is sure to have kids giggling with its “potty” humor and shenanigans.
