The Mighty Jungle is a Canadian puppet series created by Jeff Rosen and Jason Hopley. The narrative of the story is largely crafted by a group of preschoolers who appear in live-action segments interspersed between puppet-acted scenes. It is co-produced by Halifax Film and Decode Entertainment, both DHX Media Companies (now as WildBrain), and produced in association with CBC Television. The series is broadcast in Canada on CBC Television, a Canadian television network owned by the Canadian Broadcasting Corporation, the national English-language public broadcaster, in the Kids' CBC programming block, and in the United States on Sprout. In Latin America, it aired on Playhouse Disney in Spanish as Había una vez... en la selva poderosa.
