Something I thought up.

The Zomdoll are normally a peaceful, if creepy race, but if one touches ANYTHING hot, they are turned into RAVENOUS BLOODTHIRSTY MONSTERS. It only has 2 cures. The one that is know to most and 6% of others, is by allowing the sun to rise. The Zomdoll then sleeps for one day, the next day, they wake up, to find the blood from their victim hardened on their hands. They also have no idea why they get blood ontheir hands, and everyone else is too spooked to tell 'em.

Yeah, i'll do more stuff later.
