Circling Fire

The Circling Fire is an unused behavior for a type of fire. It would have circled around the player, making platforming more difficult. There is also a stubbed script associated with the Circling Fire implying there was an object attached to the Circling Fire. Some believe these are the remnants of a Fishing Boo enemy, similar to the one in Super Mario World. This draws a parallel to the unused Blargg enemy, as that also is an unused enemy originating from Super Mario World.

Manifestation
Some people have reported the Circling Fire has appeared. It most commonly appears in Lethal Lava Land or Big Boo's Haunt, but has been noted to appear in other levels, such as Bowser in the Fire Sea.

There is a 50/50 split in the appearance of the Circling Fire. Some say it is simply the fire, but others say it is a finished Fishing Boo, with a white reskin of a Lakitu holding a fishing rod that is connected to the Circling Fire.
