The Sewer Zombies are quite ugly. They are covered in sewer slime and their clothes are decayed, giving them brown and green colours. Additionally, part of their rib cage is exposed and the left eye has popped out of it's eye socket, but is still attached. Since they are Zombies, their heads can be knocked off. Sewer Zombies have a characteristic zombie limp in their movements. They commonly fall over as they walk. Sewer Zombies have a variety of ways to attacks. Usually they'll walk into their prey and start punching them. However, their arms are easily detachable, in which case they bite instead of punch and sometimes they spit a green acid-like substance at others.
