A creature with ogre-like characteristics and displays long, ratty, fire engine red hair. This creature is unable to fit in small showers and wears a size 22 shoe. Unlike regular human beings, this creature is incapable of making their own decisions, therefore follows several people around like a lost puppy. Since this creature cannot make their own decisions, they often display seperation anxiety and may ask people several questions. This creature also has a tendency to be attracted to the same sex and excrete large amounts of sweat.
