Seussical takes us into the world of Dr. Seuss, where we revisit beloved characters including The Cat in the Hat, Horton the Elephant, Gertrude McFuzz, Lazy Mayzie, and JoJo. The Cat in the Hat guides us into The Jungle of Nool where we see Horton, the kind hearted elephant who discovers a speck of dust containing Whoville. He meets JoJo, a Who child in trouble for thinking too many “thinks.” Horton decides he must protect the speck of dust on a nearby clover, while at the same time protecting an abandoned egg left to his care by the lazy Mayzie la Bird. Horton tries to convince the other animals in The Jungle of the existence of the Whos, but he is ridiculed and put on trial for insanity. Only his loyal neighbor, Gertrude McFuzz, never loses faith in him.
