From dreamy thoughts about colour to fantastic notions on left and right, this surreal book encourages young children to let their imaginations run riot and think up all kinds of weird and wonderful things.

This delightful Beginner Book now joins 16 of Dr. Seusss' most popular works in the Classic Collection series, which also contains 'The Cat in the Hat', 'Fox in Socks' and 'Green Eggs and Ham'. With Dr. Seuss's usual measure of riotous rhyme and wacky illustrations it will encourage even the most reluctant child to learn to read. 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 nearly half a million books sold worldwide.

This delightful book forms part of the third stage in HarperCollins' major Dr. Seuss rebrand programme. With the relaunch of six more titles in January 2004, such all-time favourites as 'The Lorax', 'The Foot Book' and 'Yertle the Turtle' 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. 'Oh, the Thinks You Can Think!' belongs to the Green Back Book range.
