999% Damage - Go into Training Mode in 1 Player Game. Select Mario as your character and anyone else as your rival's. Go to any level and start the game normally. Press Start and select Green Shell as your Item. Unload all of the Green Shells you possibly can into the level. Now, walk up to your opponent, and use Mario's B down move. His attack will freeze mid-way and the Green Shells will rack up 999% damage to your opponent. If you set your opponent on any move aside from Stand, this is very difficult to pull off.
