There s no denying that Sam， Pam， Will and Jill， a quartet of anthropomorphized crocodile children， have hit on an ingenious way to take full advantage of a new snowfall. Posing as principals， they call the local news station and declare a snow day. "All schools are closed!" announces the staff of Croc-O News. "Wheee!" exult Sam， Pam， Will and Jill， a few pages later. "And they sledded and sledded all day." Lakin s text is a model of comic economy， using simple vocabulary and repetition to create an ebullient， punchy rhythm. Nash s gouache-and-pencil pictures， often divided into panels to show simultaneous action among the four protagonists， giddily chronicle the events leading up to the principal ploy: the flurry of phone calls among the friends， the donning of appropriate snow gear， the crushing realization that school presents a formidable obstacle to their sledding. His crocodiles are nearly identical， but therein lies much of the dizzy humor -- every emotion is multiplied times four. Even the typography seems just right， with large， sans-serif letters underscoring the staccato pacing. A seamless work of storytelling about a classic snow job.
