Spike Balls are obstacles encountered in Hell. They consist of a pushable 'anchor' block, with an spinning spike ball that orbits around it at varying speed. Some are really fast and can stun-lock you by themselves while others seemingly don't move at all. The motion of the ball is not impeded by otherwise-solid blocks and will pass over them in the foreground, and will never run out of momentum whilst attached to the anchor. The Spike Ball itself only affect crates, pots, the eggplant, snowballs, dead skeletons, lava buckets, mobs and the player. The anchor block acts exactly like the normal pushable blocks.
