Lava Bubble

Podoboos are living fireballs that emerge from lava. They mainly appear in the Mario platformers but ocassionally appear in the Mario Party sub-series.

Mario Party
In this game, one of the minigames requires contestants to jump over a rope made up of many Podoboos. Contestants must jump over the flaming rope twenty times. If one fails to do so, he or she loses fifteen coins, and five coins go to everyone else. However, if all complete it successfully, everyone gets ten coins.

Mario Party 2
The Podoboo-rope jumping minigame returns in Mario Party 2. This time, contestants start by jumping over slow, blue Podoboos five times. After five jumps, the Podoboos turn orange and move faster. The rope keeps twiring until only one contestant remains. The winning contestant gains ten coins.
