When young Ozzy wakes up one morning to find his mother missing, the young mouse panics and rushes to find her. He spies a gray shape between the pickets of a fence: “There you are!” But when the page is turned, it turns out to be some cattails. He proceeds, espying his mother in an earthworm’s back end, a rabbit’s eye, a squirrel’s back, a hippopotamus’s ears (!) and, most dangerously, a cat’s whiskers. While the guessing game is pretty arbitrary, young listeners will enjoy the succession of die-cut reveals, and they’ll breathe a sigh of relief along with Ozzy when Mommy reappears. Although it doesn’t have the visual or verbal weight of Owl Babies, it has its own small charm. (Picture book. 2-4)
