A delightful joke, this latest book by the author of Who's There? Open the Door! revolves around Jimmy's search for a lost cap. Little flaps representing doors, drawers, and cases, are pulled away from the page to reveal boldly colored interiors--a refrigerator in utter chaos, a cat in a valise, a frog in an armchair. But nowhere is Jimmy's cap. Of course not. Jimmy's cap is on his head. A gay melange of color, mechanics, and unabashed nonsense.
