Kindergarten-Grade 2–Following a field trip to the zoo, a boy wakes up to find that everyone in his world has turned into an animal. His day grows wackier by the hour as ordinary situations are turned upside down, from breakfast with a zebra and rhino (his parents) to lions in the lunchroom and hyenas on the playground. Then, just as abruptly, things return to normal, leaving him to worry about the next field trip: a visit to a dinosaur display. While the rhyming text is unexceptional, Catrow's illustrations are full of fun, overflowing with eccentric creatures large and small that imbue the book with unrestrained merriment. A visual delight for storytimes.–Teri Markson, Stephen S. Wise Temple Elementary School, Los Angeles Copyright © Reed Business Information, a division of Reed Elsevier Inc. All rights reserved.
