Bonechill

Bonechill is the third to last boss in Super Paper Mario. He can fire ice bullets from a cannon on him, And he has ice breath that can make icicles on the ceiling. He has 80 HP and an attack of 4. He was stuck in a unknown prison in The Underwhere along with a Skellobit army. Count Bleck set him free to kill Mario (who was the hero of legend as told in the Light Prognosticus) and steal Luvbi (who was actually a Pure Heart); he failed and was shattered to bits. It is implied that he was once a Nimbi. The player can use the blue blocks on his face as a HP Gauge.
