When a boy shares his cookie with a hungry mouse, it is the beginning of a chain of events that keeps the boy busy all day long. After all, if you give a mouse a cookie, he's bound to ask for a glass of milk, for which he'll certainly need a straw—not to mention a napkin, and a mirror to check for a milk mustache, which will only lead to him noticing that he needs a haircut. All around the house, this mouse and boy find one fun thing to do after another, leading all the way back to one more cookie.

Young readers will instantly recognize—and enjoy—the everyday adventures the book details.
