Go to the pachinko mini game, where you're in the big slot machine game. To get there, go over to the docks where you enter Noki Bay, get on top of a boat and wait. When you go under the bridge theres a coin. Grab it and hover. You will enter the game. Once you're in the game, jump on the springboard and when you're almost to the top, start hovering and try and land on the piece of land before the game area. When you land on the piece of land, it will act like a slope and smoke will come from the sliding Mario, but you won't go anywhere. You can change nozzles. The only way to exit is to push start and exit the level.
