Cheeseheads were creatures that roamed the tundra near the city of Metropolis. They traveled in herds, searching for tailgates and other Arcana of the Sacred Pigskin. They were led by a lamp wearing a bell with a pink satin ribbon in a fancy bow. They were Roqueforts, and smelled bad as a result. Tundra Dawn, Cleveland, and Tremendous Ptarmigan encountered the herd during their quest for a Mammyth. The smell of the herd prompted the three to change direction.
