Pumper Cars

Pumper Cars is a Duel and single-player minigame featured in Mario Party 8. Its name is a pun on "bumper cars".

Introduction
The camera goes through part of the mine, then it comes to the first player. The screen splits into two to show the second player.

Gameplay
Players must hold the Wii Remote sideways and pump their handcars all the way to the finish. The first one to reach the goal wins. To operate the levers correctly, they must shake the up and down while holding  and. If the player doesn't hold both buttons, the cart doesn't move.

Ending
The screen then cuts to the winning player in a different perspective, who stops to do a winning pose and then continues pumping.
