Travel from the Jungle of Nool to the Circus McGurkus as the Cat in the Hat, our narrator, tells the story of Horton. Discover the Elephant who discovers a speck of dust containing tiny people called the Whos, including Jojo, a Who child, who gets in trouble for thinking too many "thinks." Horton's challenge is twofold — not only must he protect the Whos from a world of naysayers and dangers, but he must also guard an abandoned egg that's been left in his care by the irresponsible Mayzie La Bird. Although Horton faces ridicule, danger, kidnapping and a trial, the intrepid Gertrude McFuzz never loses faith in him. Ultimately, the powers of friendship, loyalty, family and community are challenged and emerge triumphant!
