Stalkoblins are enemies in Breath of the Wild.
Hyrule Compendium Entry
Stalkoblins are the skeletal remains of Bokoblins which emerge from the earth at night. When they emerge, they may be holding various Weapons. If they lack any Weapons, they will either swipe at Link if he is nearby, or dig up rocks to throw at Link.
Stalkoblins are fragile and their bodies will easily collapse if struck, leaving their disembodied skulls to roll around. Shortly afterwards, their bodies will reform and run after their heads to reattach them. If a Stalkoblin's skull is present, the bodies of other Stalkoblins whose skulls have been destroyed will remain. These decapitated skeletons will simply jump and wave at the remaining intact Stalkoblins until their skulls have been detached, at which point they will attempt to take the skull for themselves. Stalkoblins will pick up the detached skulls of other Stalkoblins and throw them at Link to hurt him. If they come into contact with a flame, their entire body will catch on fire, in addition to any wooden implements they carry.
The detached arms of Stalkoblins, known as Bokoblin Arms, can be picked up by Link and used as a Weapon. While detached, it will roll towards a common point with the other bones to reform the Stalkoblin's skeleton. If taken, Bokoblin Arms will remain animate when the rest of the skeletons they belong to are destroyed. When defeated, they may drop Bokoblin Fangs. Curiously, the Bokoblin Fangs will not drop from their skulls, but rather from their skeleton bodies.
Link may pick up a detached Stalkoblin head and kick it further away from its body. If it lands in water deep enough to submerge it completely, the Stalkoblin will die.
- "A skeletal arm that keeps moving even after it's severed from its body. It's kind of gross to strap it to your back, but it'll do in a pinch. It's old and fragile, so it's quick to break." — N/A (Breath of the Wild)
