Varusaburosu's Background/Ecology
 * In ancient times, a huge long drought hit the Desert causing the many oasis to dry up completely. Due to this long drought, Varusaburosu's ancestor moved to the harsher Volcano and evolved to fit with this harsh environment. The reason why Varusaburosu's species stayed is in the Volcano and didn't go back to the Desert is because of a particular Cactus found only in the Volcano that is this species' favorite.
