Keronpa Ball

A Keronpa Ball is an enemy found in Super Mario 64. Keronpa Balls are small black spheres that hover just above the ground. They are usually found on the edges of pathways, immobile and harmless until the player passes by, at which point they double in size and shoot a tiny fireball that chases Mario for a short time before snuffing out. If the player is hit by the flame, Mario will run around uncontrollably and steadily lose three health wedges. Two Keronpa Balls in Wet-Dry World's downtown area are unable to spit fire due to a level design flaw. This error has been reported to be fixed in some copies of Super Mario 64 by the Self-Patching Anomaly.
