Crane Minigame

By collecting a Cog from sublevel 2 and pressing the buttons for the machine in order, you can activate the crane machine in sublevel 1. Once you've turned on the crane, you can move it left by holding the Y button and back by holding the X button.

Once you let go of the buttons, it will pick up whatever is below it. You can obtain the Feeling Fine badge, the Feeling Fine P badge, and a Star Piece by using this machine.

Special 8-Bit Dressing Room

In one room of sublevel 2, to the left of the second elevator, there is an air vent opening that you can Spring Jump into. If you drop through the rightmost grate in the air vent, you'll end up in a dressing room.

Upon opening the curtain, Mario and his partners will transform into 8-bit versions of themselves, and the original Super Mario Bros. theme will play. This special effect will disappear upon leaving the room.

Teleport to Rogueport Sewers

A teleportation pod in sublevel 2 of the X-Naut Fortress can take Mario directly to Rogueport Sewers. This is located in the room to the right of the elevator from the surface and sublevel 1.

This is the only way out of the Moon. However, once you finish Chapter 7 and go back to Rogueport, you won't be able to use this machine to teleport again until you reach the postgame.
