Xylophon

Xylophon: a reanimated skeleton, named for the sound they make as they rattle. An animated skeleton is a type of physically manifested undead often found in fantasy, horror fiction, and mythical art. Though most are human, they can also be from any creature or race found on Earth, Midgard, or Middlearth.
· Animated human skeletons have been the personification of death in Western culture since the Middle Ages.
· The Grim Reaper is often depicted as a hooded skeleton holding a scythe and occasionally an hourglass.
· Death as one of the biblical Four horsemen of the Apocalypse has been depicted as a skeleton riding a horse.
· Figurines and images of skeletons doing routine things are common in Mexico's Day of the Dead celebration where skulls symbolize life and their familiar circumstances invite levity. Undead skeletons play a more active, and less symbolic, role in modern fantasy fiction. Skeletons are creatures that have been summoned from beyond the grave. They are normally of fallen warriors on battles of long past.

Skeletons might be given 'life' by a more powerful undead or necromancer. Reanimated by dark magic powers; skeleton follow their master’s orders without questioning. They appear a mindless set of animated bones, brutal and virtually immune to a piercing attack that would only harm the flesh they lack. In many stories, legions of undead skeletons are raised as perfectly obedient and expendable foot-soldiers or guards. Since most skeletons are controlled by something else, they cannot make their own intelligent decisions, and can easily be led into ambushes, traps, or hazardous terrain.
