Bumper Bubbles

Bumper Bubbles is a Free-for-All minigame featured in Mario Party 9 and Mario Party: The Top 100. Its name is a reference to bumper cars.

Introduction
The players swim in their bubbles up to the center from offscreen. They then fall back to the bottom of the screen.

Gameplay
Players float around the screen inside bubbles, trying to collect and keep as many balloons as they can, while avoiding Spiked Balls. If players collide with a Spiked Ball, all of their balloons are released, and they fall off the screen temporarily. Players can bump other players by colliding with them. Five balloons spawn every four seconds until the last five seconds of the game. After 60 seconds, the player with the most balloons wins.
