A native creature of Teledahn. It is described as a 40' killer whale type with a hard shell, but quick and agile for its size. It is very sensitive to loud sounds. Although aquatic, it is an air breather and sleeps on the surface. It feeds on flappers and the giant mushrooms found on the Age. Apparently Ventus built a gate to keep Shroomies out and protect his mushrooms. Manesmo also found a Shroomie nest.
