The stage consists of five different platforms, and takes on a very symmetrical appearance. The main platform floats in the middle of the Geothermal Power Plant, while four soft platforms - two on the left and two on the right, with one located above and slightly to the right of the one below it - float above it.
Despite being a relatively simple-looking stage, fighters have to deal with a myriad of different hazards during a battle. The main hazard fighters will have to deal with is Ridley, whom appears as a boss character on the stage. Ridley will attack fighters with various claw swipes, jump attacks, and fire-based attacks. Ridley can be defeated, but will respawn over time. In timed matches, KOing Ridley grants the fighter a point, just as they would gain from KOing another fighter. In addition, Ridley can ally with a fighter that deals enough damage to him.
Several other enemies from Other M may periodically spawn on the stage, namely the FG II-Grahams, Joulions, and Zeros. The Zeros will crawl around slowly on the ground, but can be picked up and lobbed by fighters; the FG II-Grahams will fire bolts of energy forwards when attacked; and the Joulions inflate and explode after being attacked.
