Who tracked the muddy footprints all through the house from the yard clear to the bathroom? Page by page, lifting flaps reveal everyone who didn't do it, from the puppy in the doghouse to the horse outside the window to the mice under the stairs. Each scene occupies a good two-thirds of the spread, generous white space acting as focus for the action as the gloppy prints lead into and out of the soft-bleed setting, as well as backdrop for the one simple statement, printed in a large, black typeface, per opening: "Someone has made muddy footprints in the kitchen" (or up the stairs, or in Rabbit's room, etc.). Given that readers have already seen Parsnip happily walking through the mud on the title page, the final reveal of the bathing lamb will surprise only the very young. But that's who this is for: Toddlers will enjoy identifying the various animals under the flaps and chiming in with each subsequent "Not me!" And the cause-and-effect complexity of the tale is developmentally just right. (Novelty/picture book. 1-3) (Kirkus Reviews)
