Plot Elements

 * In the land of the Cubivores, the beast known as the Killer Cubivore reigns at the top of the animal food chain. This powerful tyrant and his gang of cronies have gorged themselves on the essence of the land, known in the game as "Wilderness", so much that they have absorbed some of it into themselves.
 * Meanwhile, nature has begun to fade away, becoming drab and infertile, and the number of beasts has declined.
 * A Cubivore has taken it upon himself to become King of All Cubivores, in order to challenge the Killer Cubivore and restore the Wilderness to the world.
 * The Cubivore overthrows Killer Cubivore as the King Cubivore and helps the Cubivore species return from endangerment.
