Balloon Trip (minigame)
From the Super Mario Wiki
The player must use the Wii Remote and Nunchuk to flap left and right in this game. This will help the character fly across the stage and collect balloons to earn points. A balloon is worth ten points and getting ten balloons bring in 100 bonus points. Also, popping an opponent's balloons give the player more bonus points. If the player fly 1000 yards, they will get a bonus. The player must avoid letting their character fly close near a spark or the water (where a Fish will come to try to eat him).
This is the 3D version of Balloon Trip from the NES game Balloon Fight. Flap your arms to fly through the sky. If you pop 10 balloons in a row, you might get a bonus! Connect the Balance Stone to play.
