A telling-time adventure for ages 3 to 8 Mr. Crocodile has big plans for finally catching--and eating--five pesky monkeys,   but those little rascals dupe him again and again. By the time the clock strikes six, those mischievous monkeys actually  teach Mr. Crocodile a thing or two about friendship . . . and about having fun! Judy Sierra has been writing laugh-out-loud, read-aloud picture books for 25 years. She has worked with some of the cleverest illustrators, like Marc Brown, Melissa Sweet, J. Otto Siebold, Will Hillenbrand, and two-Caldecott Award winner Stephen Gammell.   Judy's books are for ages four to eight. They aim to stretch children's vocabularies, tickle their funnybones, and extol the virtues of kindness, perseverance, friendship, and the joys of a life filled with books.   "I try to create stories and rhymes that will entice children ages four to eight," she explains, "but I know that picture books are shared across generations. So I alwasy add a bit of sly humor and wordplay for adults. I'm especially pleased when an online reviewer says they don't mind reading my books again and again."   Judy Sierra lives in Portland, Oregon, with her husband Bob and their library-card-carrying poodle, Keiko.
