If I Ran the Zoo welcomes yong readers to the crazy world of Gerald McGrew, who dreams of transforming his local zoo into a madcap menagerie of wierd and wonderful beasts. His New Zoo, McGrew Zoo would be "better than Noah's whole Ark", with an amazing array of animals, ranging from the incredible Thwerll, whose legs are snarled up in a terrible snerl, to the family of Joats, whose feet are like cows' but wear squirrel-skin coats! This delightful book forms part of the second stage in HarperCollins' major Dr. Seuss rebrand programme. With the relaunch of 10 more titles in August 2003, such all-time favourites as How the Grinch Stole Christmas!, Mr. Brown Can Moo! Can You? and Dr. Seuss' Sleep Book boast bright new covers that incorporate much needed guidance on reading levels: Blue Back Books are for parents to share with young children, Green Back Books are for budding readers to tackle on their own, and Yellow Back Books are for older, more fluent readers to enjoy. If I Ran the Zoo belongs to the Yellow Back Book range.
