At 7 AM, the crocodile’s alarm goes off. He slowly gets out of bed, brushes his teeth, chooses the perfect tie, eats his breakfast, and heads out the door. He’s a Professional Crocodile (Chronicle, $17.99) and he’s off to work with the other city dwellers, hurrying down sidewalks and cramming onto crowded trains. Giovanna Zoboli and Mariachiara Di Giorgio show humans and animals commuting in perfect (and perhaps oblivious) harmony in this wordless picture book that will leave onlookers hunting through the illustrations for hidden faces and familiar scenes that all lead to a chuckle-worthy ending. Ages 4-8.
