I made a MK7 community called Balloon Raiders. Basically it is a balloon battle where you use mushrooms to bump into your oppoments, making them lose a balloon and you gain it for an extra hit. You can only get mushrooms, Triple Mushrooms, and if you are very lucky, a Lucky 7 with only Mushrooms. To join, start up your MK7 game, go to Online Multiplayer, then Communities. Then scroll up and go to Search By Code. Then type in 66228420642320. I hope to see you there!
