Seussical, sometimes Seussical the Musical, is a musical with lyrics by Lynn Ahrens, music by Stephen Flaherty, and a story co-written by both. It is based on the works of Dr. Seuss, with most of its plot drawing from Horton Hears a Who!, Gertrude McFuzz, and Horton Hatches the Egg. The title is a portmanteau of "Seuss" and "musical". Despite a negative critical reception and significant financial losses during its initial Broadway run in 2000, Seussical has since had a revival in popularity, with two US national tours, a West End production, and numerous adaptations for schools and regional theaters.
