The hungry dead are undead corpses that return from the grave to feed off the living.  Like zombies, they fight until destroyed or turned away.  The look exactly like zombies in all respects… except that these zombies want to eat the living.

Such is their unnatural hunger that once a victim is slain, 2-5 hungry dead will stop attacking to feed on the slain victim.  Hungry dead will not eat other undead, only fresh slain corpses.

Combat
    Hungry dead fight as zombies, mindlessly hammering at their foes to fell them so that they can eat them.
     Damage Reduction 25/Critical Area:  The animating force is always concentrated in one single area of the body.  Except in that area, usually the head or the heart, the hungry dead are fairly immune to physical attack.  A critical hit is necessary before a character figures out where that area is.  After that, a called shot will always hit the critical area.
     Undead:  Immune to mind-influencing effects, poison, sleep, paralysis, stunning, and disease.  Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.
     Immunities: Bloody bones have cold immunity.  Because they lack flesh or internal organs, they only take half damage from slashing or piercing weapons.
