Soap Surfers

Soap Surfers is a 4-player and duel minigame included in Mario Party DS. In this minigame, as the title literally suggests each character surfs upon a bar of soap, and attempt to knock each other out of the sink.

Setting
The game takes place in a bathroom sink, with each character riding upon their own soap bar that come tinted in their corresponding colours. Bubbles can also be seen floating in the background, as well as a mirror.

Gameplay
The aim of the game is to knock out your opponents by slamming onto them to push 'em off the sink; defeat all your opponents, or just be the last one standing. Use the control pad to steer the soap as it rides down the sink.
