Skelington Bone is an enemy from Battletoads in Battlemaniacs.
Skellington Bones appear as tall skeletons carrying a shield. During the first stage, Khaos Mountains, heads will pop out of the lava holes forming this skeletal being, which uses its shield to bash the player up. They're tougher than the regular Porka Pigs in the stage, but can be easily disposed of by being pushed into the pits. Curiously, if they're hit by another enemy they'll start to pursue it and ignore the player for a while.
