Flame thrower (Flame Chomp)

A Fire Spitter is an obstacle found solely in Super Mario 64. They are tiny black spheres that hover in place a tiny distance off the ground. They usually line the edges of pathways. A Fire Spitter is perfectly motionless and harmless until Mario passes by. Then it expands to about twice its size and shoots a tiny fireball that chases Mario around. If hit by the flame, Mario will run around uncontrollably while steadily losing three life pieces. Fire Spitters can only be destroyed if Yoshi eats them in Super Mario 64 DS.

There are two Fire Spitters located in the downtown area of Wet-Dry World. However, due to a mistake in the level design, they cannot spit fire. Even at its shallowest point, the water level in the area is high enough that the two Fire Spitters are submerged, rendering them completely harmless.

Trivia

 * In Super Mario 64 DS, motionless Fire Chomps replace Fire Spitters.
