A Skeleton is a very common hostile mob that shoots arrows and drops 0-2 bones, 0-2 arrows, and or a bow (most

likely used, but sometimes enchanted) upon death. They are the primary ranged mob the player encounters. Skeletons are currently only one of two mobs that drop bones, the other being a Wither Skeleton. They may also spawn with a 20% chance in the Nether, replacing a Wither Skeleton.
