Eyes look at you from many places (there's even one on the left thumb!), showing no signs of a mind, only a rage caused by maddening pain and suffering. As you look, the body twists into other unnatural shapes, growing arms and legs spontaneously, the head twisting and disappearing into the back while a grinning mouth bearing needle-thin teeth opens where proper humanoids have a navel.
