Go to the stage creator. Select a big stage and put in a long ledge with no holes or pits and some stairs. Above the ground, place three of the moving floor things side-by-side. Place ladders at both ends of the lower platform, leading high enough to jump from the ladder to the moving platform. Make sure the ladders are not under the moving platform. The only items that should be put in are Super Smash Balls, Cracker Launchers, and Bunny Ears. Place a few small platforms between the moving platforms and the lower platform with the ladders. This is a great arena for Sonic's Spin Dash move and Homing Attack, as well as for Mario because there are no walls to stop either one from being knocked out of the arena. The best game play mode for this stage is Team Brawl, with two Sonics vs. Mario and Luigi, another Mario, or Dr. Mario.
