Jane Kangaroo was a recurring character on The Wubbulous World of Dr. Seuss. The character's roots lie in the 1954 Dr. Seuss book Horton Hears a Who, where the chief antagonist was a nameless, sour kangaroo who refused to believe Horton's tale and feared that he was a menace to the whole jungle. In the 1970 animated adaptation of the book, the kangaroo was christened Jane, and the name was retained for Wubbulous World.
Like her literary portrayal, Jane is a snobbish matron, and the mother of Junior Kangaroo, and resides in the Jungle of Nool. Her valuing of the status quo and insistence on order occasionally precipitates crises. Notably, in "The Mystery of Winna-Bango Falls," Jane orders the Winna-Bango Falls residents to stop playing with fruit peels and instead to throw them away, causing an environmental catastrophe.
