Flame thrower (Flame Chomp)

A Keronpa Ball is an obstacle found in Super Mario 64 and its portable remake, Super Mario 64 DS. Keronpa Balls are tiny black spheres that hover in place a tiny distance off the ground. In the remake, they have faces based on Fire Chomps. They usually line the edges of pathways. A Keronpa Ball is motionless and harmless until the player character passes by. Then, it expands to about twice its size and shoots a tiny fireball that chases him around for a short time until it goes out. If hit by the flame, the character will run around uncontrollably while steadily losing three life pieces, although he will still be able to jump. In the remake, Yoshi will also be able to breathe fire if he swallows a Keronpa Ball.

Keronpa Balls appear in the following levels:
 * Vanish Cap Under the Moat
 * Hazy Maze Cave
 * Shifting Sand Land
 * Dire, Dire Docks
 * Bowser in the Fire Sea
 * Wet-Dry World
 * Tiny-Huge Island
 * Tick Tock Clock
 * Rainbow Ride
 * Bowser in the Sky

There are two Keronpa Balls in the downtown area of Wet-Dry World. Due to a mistake in the level design, however, they cannot spit fire. Even at its shallowest point, the water level in the area is high enough that the two Keronpa Balls are submerged, rendering them harmless. They can be activated using glitches, though. By using the water-raising/water-lowering glitch, the water can be made to go lower than normal, so they can be activated. Due to being useless, these Keronpa Balls were removed in the remake.
