Seussical is about Horton the Elephant, who hears a small dust speck speak. The Dust speck is actually the planet of Who. Horton makes fast friends with characters such as JoJo, a small Who, who thinks strange "thinks" and invents strange creatures. Also along on the journey is Gertrude McFuzz, and her one feathered tail. And Mayzie LaBird, her fabulous tail, and the egg, which she forces upon Horton. Part of the 2010 Children's Studio Series.
