From the game Super Mario Sunshine for the Nintendo Gamecube

Go to the pachinko mini game, where you're in the big slot machine game. Jump on the springboard and when you're in the game, hover over to the side where you won't go into any slots. You will fall out of the game and die. But as you are falling out of the game, start hovering. You will hit an invisible barrier under the game that will stop you from hovering, however the hovering sound will still continue.
