Bowser's Castle is a starter stage in Super Smash Bros. Revolution. It is based off the final Bowser boss fight area. It consists of a big platform in the center and two walk-off platforms right next to it. Occasionally lava bubbles will appear, and touching one will give you 8% damage. On the right side of the stage there is a lever, which if hit, will cause part of the center platform to fall. If the lever is hit enough times, or is hit with an unusually strong attack, the entire platform will fall. The platform will eventually regenerate, and touching the lava below it will cause 18% damage and high knockback.
