Droopers are fairly similar to drippers. The Distinguishing feature here is that the skin has come loose and is sort of hanging down. A person with a regular build will appear to have a flap of skin hanging over their belt line once the skin starts to sag. The jowls and face droop down and the skin may split and come away from the bone like on the top of the head. This kind of zombie will have flappy arms like your grandmother only not from old age. As with all of these nasty creatures, stay well clear if possible and dispatch them from a distance.
