Seussical

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".
