As Duke Igthorn plans an attack on King Gregor's castle, Cavin (a page in the castle) is left in the woods after some of Igthorn's ogres run off the Humans. The Gummi Bears find Cavin passed out in the woods with a Great Gummi Medallion, that was left to him by his grandfather. When he proves he is a friend, the Gummi Bears and Cavin team up to stop Igthorn's plans.
