The Marvelous Land of Oz is a 1981 musical play by Thomas W. Olson, Gary Briggle, and Richard Dworsky, based on the 1904 novel by L. Frank Baum. Not long after the events in The Wonderful Wizard of Oz, a young boy named Tip is the unhappy servant of Old Mombi, a wicked Sorceress in the Land of the Gillikans (in the north of Oz). One day Tip escapes, after creating a walking stick figure with a jack-o-lantern head named Jack Pumpkinhead with a magic Powder of Life stolen from the witch. He goes to the Emerald City, now ruled by the Scarecrow, but unfortunately, a female Army of Revolt, 400 strong and led by General Jinjur, captures the city. The Scarecrow, Tip, Jack, and some other oddball characters flee the city and head west to the land of the Winkies, now ruled by the Scarecrow's old friend the Tin Woodman. They must recapture the Emerald City, defeat Old Mombi (who allies herself with Jinjur), and most of all, discover the true secret of unassuming young Tip.
