Yagyu (The Holes in Your Nose, 1994, etc.) focuses on another part of the body that doesn't get much attention from adults, in a book that was first published in Japan in 1982. The narrator compares his feet to those of adults, to apes' feet, and to horses' hooves. An interesting nugget for readers to take away is the image of a foot having treads, like sneakers or tires; a sequence drawing shows in "stop motion" how a runner's foot hits the ground (heel, whole foot, toe). The simple line drawings, plain colors, and design recall old titles in the Let's-Read-and-Find-Out series—utilitarian at best. Two pages invite readers to make foot tracings and foot prints, enticements that may limit the book's longevity in school or public libraries.
