Mount Duel
From the Super Mario Wiki
Mount Duel is the name of a mini-game found in the Mini-Game Mode in Mario Party 6. This mini-game is hosted by Twila. It is a four-player tournament where players compete to reach the top of the massive mountain known as Mount Duel. To play Mount Duel, the player must have collected at least one Duel Mini-game.
The four characters climb one large rock and then two characters compete in one Duel mini-game. The winner climbs another rock, while the rock the looser was standing on, crumbles, making the looser fall down to the bottom. Then, the two other characters compete in a mini-game as well, and again, the winner clims a rock and the looser falls down.
Then, the two loosers compete againts each other, to find out which of the two end up in third place and who ends up in fourth place. Then, the two winners compete, and the winner climbs to the top and is the winner of the mini-game. Meanwhile, the looser gets second place.
