Sergeant Cast Iron is a Murk Gourmand. He has a swampy-green body with a tan belly like all Murks. He is slightly thicker and pudgier than other Murks. He also has a more prominent brow and jowels, and a prominent lower jaw compared to other Gourmands. His voice is also much deeper than most Murks.
Powers and Abilities
Like all Gourmands, he has several acid filled stomachs and multiple long tongues so he can eat massive amounts of inorganic matter with ease.
