Seussical is a musical comedy by Lynn Ahrens and Stephen Flaherty, based on the many children's stories of Dr. Seuss, with most of its plot being based on Horton Hears a Who!, Gertrude McFuzz, and Horton Hatches the Egg while incorporating many other stories. The musical's name is a portmanteau of "Seuss" and the word "musical". Following its Broadway debut in 2000, the show was widely panned by critics, and closed in 2001 with huge financial losses. It has spawned two US national tours and a West End production, and has become a frequent production for schools and regional theatres.
