The people of Fire Eyes' Village rely on the heat of the Volcano to survive, but recently it has begun to cool, and Raptors and Vipers have begun to roam the Volcano's outskirts. Finding the source of these problems is the main story arc of Prehistoria.
The Hero and his Dog journeyed into the Volcano and found an evil clone of Elizabeth was the one who had taken control of the dinosaurs, and intended to cause an ice age to kill off Elizabeth and her people so the dinosaurs could take over the region. The clone sicced her "pet rock," Magmar, on the hero, but Magmar was destroyed. Angered, the clone overloaded the Volcano, causing it to erupt and catapult the hero into Antiqua.
- Mud Pepper (defeat Viper Commander)
- 900 Talons (defeat Magmar)
After defeating Magmar, the interior of the Volcano becomes inaccessible. Using cheat codes to re-enter it, all enemies will be gone from the main chamber, but they are still in the side rooms, and the Viper Commander miniboss will spawn normally if the player goes through the rooms to where it would appear. This also means the player can still find the man that teaches the Speed spell and learn it from him.
