Well, the other day, with my brother's little wrestling ring model with realistic ropes, I created what I call "The KWF: Apook is Koopa"
I had Mario and Luigi fight after an argument about who was stronger. It was kinda interesting, cause no one has to win, and you can make them battle any way you want. Then I had Bowser and Wart fight, as well as Toad and Wooster. You guys should try it
