Join Dr. Seuss and let your imagination run wild in this classic story to encourage the most out-there thinkers! Think left and think right, think low and think high! Learn to explore the fantasy world of the imagination with a little help from Dr. Seuss. With his unique combination of hilarious stories, zany pictures and riotous rhymes, Dr. Seuss 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 ranking among the UK's top ten favourite children's authors, Seuss is firmly established as a global best-seller, with over 600 million books sold worldwide. As part of a major rebrand programme, HarperCollins is relaunching Dr. Seuss's bestselling books, including such perennial favourites as The Cat in the Hat, Green Eggs and Ham and Fox in Socks. In response to consumer demand, the bright new cover designs incorporate much needed guidance on reading levels, with the standard paperbacks divided 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. 'Oh, the Thinks You Can Think!' belongs to the Green Back Book range.
