Canon:Corpse gatherer

The Corpse Gatherer is an undead creature in the Dungeons & Dragons role-playing game. It appears as a giant made of earth and stone. Upon closer inspection, one can see headstones, dead hands and heads protruding from its bulk. The monster is essentially an animated graveyard. A corpse gatherer is usually neutral in alignment.

Powers and Abilites
A corpse gatherer can swallow any creature in its grasp. The victim then takes bludgeoning damage from rocks, gravestones, etc. in the creature's body. It can also increase its mass by absorbing corpses.

When a corpse gatherer is destroyed it falls apart into its component corpses. The undead's animating force converts these corpses into zombies.
