Not undead per se, these animated skeletons are the festive spirits of the ancestors of various Central American communities. Allowed back to the mortal plane for a single night on All Hallows Eve they roam the vicinity of their resting places and former homes not in search of living flesh or human brains but in search of FIESTA! The only true danger they pose is if they decide to "help" one along the path to becoming an ancestor oneself!
