The stage is a completely flat surface with a medium-sized structure above the middle of the floor acting as a ceiling. When hazards are on, the ceiling is destructible through two methods, which are by either damaging it with an attack, or having an opponent collide against it when they're being knocked back. When destroyed, it gets replaced with a single soft platform on the middle of the stage until it is eventually rebuilt. When stage hazards are turned off, the structure becomes indestructible.
Occasionally, the Old Man paraglides onto the tower, stays for some time, and then paraglides away from the tower. He can also occasionally be seen gliding in the background behind the tower. He does not affect the battle.
