Thidwick the big-hearted moose is happy his antlers "can be of some use" to a menagerie of animals who move in and make themselves at home. "A host has to put up with all kinds of pests. For a host, above all, must be kind to his guests."

With his unique combination of hilarious stories, zany pictures and riotous rhymes, Dr. Suess has been delighting young children and helping them learn to read for over fifty years. Creator of the wonderfully anarchic Cat in the Hat, and ranked among the UK's top ten favourite children's authors, Dr. Seuss is a global best-seller, with nearly half a billion books sold worldwide.

As part of a major rebrand programme, HarperCollins is relaunching Dr. Seuss's best-selling books. In response to consumer demand, bright new cover designs incorporate much-needed guidance on reading levels. The standard paperbacks divide into three reading strands - Blue Back Books for parents to share with young children, Green Back Books for budding readers to tackle on their own, and Yellow Back Books for older, more fluent readers to enjoy. This is a Yellow Back book.
