Podoboos (also known as Fire Snakes) are obstacles, and they can be found on Grumble Volcano in Mario Kart Wii, and on the Mario Kart Wii version of Desert Hills from Mario Kart DS (they are only fireballs in the original). They hop back and forth on the track. If they are touched by a racer, the racer will spin out. On Grumble Volcano, Podoboos come from pipes, but on DS Desert Hills, the sun spews them on the track. In Waluigi Stadium and DS Wario Stadium, players would have to dodge Podoboo Cogs. In Mario Kart 8, the remake of DS Wario Stadium includes Podoboo Cogs in the same place as last time. However, when racing on the track, you can not see them fully as they act as a hazard between the new anti-gravity section, where each line of the Podoboo Cog comes up only once at a time.
