Bumper Balls

Bumper Balls is a minigame in Mario Party and Mario Party 2. In it, players roll around on personalized balls and try to bump each other off a platform. In Mario Party 2  there are three levels for the players to compete in and they each have different challenges.

Level One
Level One takes place on a platform surrounded by lava. It is a basic level.

Level Two
Level Two takes place on an icy mountain. In the middle is a Fly Guy frozen in ice. It can be very slippery on the mountain, so players must take care not to slide off.

Level Three
Level Three is on a floating isle in the ocean. Characters bumped off are carried away by Bloopers. The isle contains rocks and bumps which can change slightly the speed when rolling over them.
