Podoboo Cogs (also called Podoboo Chains, Firebars, Fire Rods, Fire Cogs, Fire Traps, Fire Arms, or simply Spinning Fireballs) are chains of fireballs that spin around endlessly. Usually they're connected to a hard surface while other times, they float in mid-air. While there is usually one Podoboo Cog spinning, there can sometimes be two Podoboo Cogs connected to each other or sometimes even three. If they make contact with Yoshi, they can cause damage and even knock Baby Mario right off his back forcing Yoshi to retrieve him.

Podoboo Cogs return in Super Mario Galaxy 2. In this game, they spin across the ground and are usually found in Bowser and Bowser Jr. Galaxies. They also appear attached to Bowser Jr.'s Boomsday Machine.
- Yoshi's Island DS was the first game in the Yoshi series where they were listed under the name Podoboo Cog, previously various other games (such as Mario Kart: Double Dash!!, Super Princess Peach, and New Super Mario Bros.) had them listed as such.
- Their name seems to suggest that they are actually Podoboos formed as a spinning chain.
