These crotesque monsters live and thrive in places where dung, rubbish, and filth can be found. They are three-legged creatures with two tentacled arms used to shove piles of rubbish into their large, toothy mouths. His sensory organ stalk is sensitive to bright light and direct sunlight, so that the monster can only be found underground. Some burgomeisters have attempted to put these creatures into the sewer systems of their cities - a big fault, because sooner of later the monsters escape and wreck havoc in town.
