Jack O' Bones, also known as Bone Thrower, is an enemy in the Castlevania series. They are skeletons that tie their dislodged bones together to form their own version of the Cross Boomerang, which acts somewhat like 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.
