Teague trots out his goofy imagination yet again, this time in a story about a familiar grade-school fixture, the lost and found. While sitting outside the principal's office anxiously awaiting what they know will be an unpleasant interview, mischievous Wendell and Floyd meet Mona, who seems to have lost her hat. They don't pay much attention until she disappears, headfirst, into the lost-and-found box. After hesitating but a minute, they follow, finding themselves in an odd place, which has not only a cave, a subterranean lake, and a hallway with many doors but also a room full of hats. Teague's lost-and-found land hasn't quite the fantastical visual flair of the realm he created for Audrey Wood's Flying Dragon Room (1996), but children will still love the crazy notion at the heart of the story, and the vivid, color-saturated double-spread paintings have lots of energy and child appeal, as well as a few delightfully silly surprises.
