Kawa-tri are bulbous, tree-like creatures that live in forests. They thrive in the shade of other trees and grow much faster when they are standing near other kawa-tri. When a kawa-tri senses that it is in danger, its entire body will harden, effectively turning it into a tree. This makes it difficult for predators to eat it, as the tough bark is not easily digested. However, kawa-tri will sometimes harden to protect themselves from the rain and will die if left too long in this state.
