Jack O' Bones, also known as Bone Thrower, is an enemy in the Castlevania series. It is a skeleton who specializes in throwing attacks.


Skeletons that tie their dislodged bones together to form their own version of the Cross Boomerang and which behaves similar to a Ricochet Rock. When they throw the crossed bones onto the ground, they begin rebounding around the room repeatedly until destroyed.

There are two variants of this monster: white ones that throw fast, low-bouncing bones, and brown ones that throw slow, high-bouncing bones. Other than their attacks, both variants have identical stats.
