From a distance, an eeno appears indistinguishable from a lumpy pile of snow, and is rarely found not among snow or ice. Its body is in fact almost entirely snow. When agitated, an eeno's body forms a face with glowing yellow eyes to see, and large arms—though it lacks legs, and still mostly takes the form of a snow pile. It wildly attacks any foreign creatures that enter its territory, usually with powerfully-hurled packs of snow or ice it has gathered from the surrounding environment.
