Following up on the success of Gomi's Everyone Poops (1993), Kane/Miller's latest Japanese import explores another child- intriguing topic in similar unblushing detail. Yagyu considers nostrils' shape, placement, and varied functions in different animals and in people, moving on logically to the effects of colds and such fascinating subjects as snot, nosebleeds, and nose hair. The graphically bold, childlike illustrations include a fairly clear diagram of nasal passages; neatly incorporated tips on hygiene round out a book that gives children some seldom- offered information about themselves in a playful yet forthright style that will both amuse and inform them. (Nonfiction/Picture book. 4-8)
