Flame thrower (Flame Chomp)

A Fire Spitter is an obstacle found solely in the games Super Mario 64 and Super Mario 64 DS. 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 pefectly 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 cannot be destroyed by any means, but avoiding them is not particularly challenging.

Wet-Dry World
A unique feature of Wet-Dry World is the ability to change the water level in the course using small diamond-shaped switches. There are two infamous Fire Spitters located in the Downtown area of Wet-Dry World; however, due to a mistake in the level design, they are useless. 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, the Fire Spitters closely resemble Fire Chomps.
