One of my fav battle mini-games even though I fail at it. XD
How to Play: OK, you see the doors? You have to get the right key to match each door, but the thing is, is there there's always less keys than players. So, you have to go quickly to get the key, and if you didn't get any keys, then your going to have to punch the player with one of the keys, that'll make em' drop it and get stunned for like a sec.
Tips: I suggest going on the side, y'know? Grab the key that's closest to you, and try to move to the side a little, y'know? People can't get you that way.
