Igthorn has finally conquered Dunwyn. With most of the other Gummis either captured or missing, Zummi must rally their comrades in Ursalia to liberate the kingdom and stop Igthorn once and for all.
Tropes:
- Bittersweet Ending: The Gummi Bears succeed in thwarting Igthorn's scheme, as well as wreck his castle, but Gummi Glen was destroyed forcing the Bears to move to Ursalia. What's worse is that Igthorn still has the knowledge of the Gummiberry juice so once he has reassembled his forces, he's going to continue the plan again. Even more depressing, Zummi was forced to signal the Great Gummis to return to their homes, realizing it's not as safe as he previously thought. However, the Great Gummis promise to come back one day and the Gummis eagerly imagine the day that they do.
- Grand Finale: This is the final produced episode for the series.
- Hoist by Their Own Petard:
- Gusto unleashes the same termite Igthorn uses against him and his army.
- Igthorn's Gummiberry-producing machine is the sole reason his castle is destroyed.
- Trash the Set: After Igthorn caused the destruction of their home in the previous episode, the Gummis return the favor by destroying his castle.
