In one hilarious pop-up extravaganza after another, one little boy who's looking for his mommy wanders into a cuckoo house full of monsters. They're all there: a mummy, vampire, werewolf...but no matter how scary these monsters are, there is no besting a little boy who is looking for his mommy. The book is illustrated by Maurice Sendak, with scenario by Arthur Yorinks and paper engineering by Matthew Reinhart. This book received the 2007 Oppenheim Toy Portfolio Platinum Award.
