Bumper Balloons

Bumper Balloons is a 2-vs.-2 and Duel minigame found in Mario Party 8. Its name is a pun on "s." It takes place in a similar setting to Kartastrophe, albeit on a differently-shaped track more fit for battles.

Introduction
The camera focuses in on each team/player before zooming out to show the entire driving area, at which point the minigame begins.

Gameplay
Players must hold the Wii Remote sideways to play this minigame. The objective for the player is to pop all of their own (team) color's balloons before the opposing team/player can pop its/theirs. To pop a balloon, a player must simply drive into it. The player must be careful not to pop the other team's/player's balloons. Whichever team/player has all its/their balloons popped first wins the minigame.

Ending
The vehicles are parked in the center of the track, and winners do victory poses while losers do losing poses.
