Prince Zingle is the oldest son of the King and Queen of Mo and, according to Smith's History of Prince Zingle, he has a great passion for flying kites. Since no one dies in the Valley of Mo, Prince Zingle will never be king. However, he once tried to take over the kingdom by pushing his father down a deep hole. He was punished by being banished to the Fruit Cake Island in the Rootbeer River where he ate so much fruitcake that he became sick and repented of his crime.
