Treadmill Grill is a mini-game that appears in Mario Party 3.
The gameplay for this mini-game is similar to the mini-game Lava Tile Isle in Mario Party 2. The characters are located in a giant room that contains a giant treadmill-like platform in the center. Situated around the outside of the grill perimeters are blue-colored Podoboos. At the start of the mini-game, the players will be situated in the middle of the giant treadmill. The little platforms of the treadmill will move in different directions, deterring the characters from standing still on the platforms. The objective of the mini-game is for the player to knock out their opponents by using a wide variety of attacks. They can jump, kick, punch, ground pound, and perform a jump kick. As the mini-game progresses, orange-colored Podoboos will start to wander around the treadmill platforms. At the same time, the treadmill will begin to decrease in size, causing the playing field to shrink. The player is eliminated from the game by either touching on the blue Podoboos on the perimeter of the treadmill, or by making contact with one of the orange Podoboos. The last character remaining will win the mini-game.
