Instructions
Launch "New Super Mario Bros." on your Nintendo DS.
Select "Minigames" from the "New Super Mario Bros." main menu.
Select "1 Player."
Select "Action" on the left side of the screen.
Select "Balloon Race." Tap the lower screen on the Nintendo DS to start the mini-game.
Blow into your Nintendo DS's microphone to send Yoshi skyward. The object of the game is to get as high as possible in 20 seconds while avoiding the enemies. Touching an enemy decreases the amount of time and pops a balloon. The game ends when both balloons are popped or time runs out.
