What Time Is It, Mr. Crocodile? Illustrated by Doug Cushman. Harcourt, 2004.


What Time Is It, Mr. Crocoile? is a story about telling time, about making a schedule, and (at the very end) about editing. Mr. Crocodile is a little bit like me. No matter how carefully I plan my day, something goes wrong.

"Down by Bristlecone Bay, where the wiffle fish play,
Mr. Crocodile, Esquire, was planning his day."

Some of the things Mr. Crocodile plans are normal, such as going to the library or shopping for food. Others are icky, like eating seaweed ice cream. Some are downright awful: He plans to catch, eat and cook the monkeys who tease him every day. Fortunately, monkeys are smarter than crocodiles, and at the end of the day, Mr. Crocodile is busily editing his schedule to include playing with his new best friends.

The hour-by-hour plot of the story is loosely based on an old children's tag game, "What time is it, Mister Wolf," in which the players tease the child who is playing the part of the wolf, until the wolf suddenly chases them and tries to catch one of them.
