Tom Terrific was an early animated series on American television, presented as part of the Captain Kangaroo children's television show. Created by Gene Deitch under the Terrytoons studio (which was a subsidiary of CBS), Tom Terrific ran in a series of five-minute cartoons created specifically for the Captain Kangaroo show from 1957-1959, and was rerun on Kangaroo for years thereafter. Drawn in a simple, even clumsy, style, it featured a gee-whiz boy hero, Tom Terrific, who lived in a treehouse and could transform himself into anything he wanted thanks to his magic "thinking cap" funnel hat, which also enhanced his intelligence. He had a comic lazybones of a sidekick, Mighty Manfred the Wonder Dog, and an arch-foe named Crabby Appleton, whose motto was "Rotten to the core!" Other foes included Mr. Instant, the Instant Thing King; Captain Kidney Bean; Sweet Tooth Sam, the Candy Bandit; and Isotope Feaney.
