Shortly after Dorothy Gale leaves Oz after her first visit, the wicked witch Blinkie awakens a gigantic Sand Serpent from the Deadly Desert to conquer Oz. Glinda solicits the aid of the Scarecrow, the Tin Woodman, and the Cowardly Lion to stop her; but to succeed, they must find the Amber Flute, which will put the monster to sleep again. Other villains, however, including an evil magician named Ozwaldo, pursue the Flute as well.
