From the Cat in the Hat in his striped chapeau to ”yawning, yearling, young, yelping” Yurkle on the create-a-character page, Seussville ( is all things Geisel. Theodor Geisel, that is, a.k.a. the late Dr. Seuss, creator of 49 cartoon-and-rhyme books that have been a mainstay of bedtime reading for children and parents for nearly 50 years. Sponsored by Random House, the site is a testament to the nonsensical whimsy that saturates the good doctor’s works. Besides the requisite games and puzzles, you can click on ”Ask the Cat” and receive E-mail replies to such age-old questions as ”Have you ever heard a Who, or has only Horton heard them?”; print out and embellish a My Many Colored Days bookmark; test your Seuss IQ; and — natch — order books and a Seuss CD-ROM. Even a Grinch couldn’t help but smile after a visit to Seussville. B+
