Oskurgis are frog-like creatures that make their homes in the nutrient-rich mud piles found in the swampy forests of the world. Since their skin has a weak, porous texture and is very sensitive to sunlight, oskurgis prefer to remain inside large shells for the whole of their lives. They are very easily frightened and have no defense mechanism other than to curl up into their shell and sink underwater. Although no one knows why, there are some rare flowers that only ever bloom in the presence of an oskurgi.
