Luigis Mansion 3DS Cheats and Tips

In the Mansion there are 2 Secret Treasure Rooms in the Mansion which when accessed, yield a lot of Treasure. These rooms are the Hidden Room (accessible starting in Area 2) and the Sealed Room (accessible from Area 4).

Hidden Room:

In the top-right corner of the Butler's Room is a mousehole. Search it with the GameBoy Horror to access this room. You will leave the same way.

Sealed Room:

Climb the right-most chimney on the roof and head inside it to access this room. To leave, uncover the mirror and use the Mirror Warp trick.

Throughout the Mansion there are fake doors which will slam Luigi against the wall causing damage and make him lose coins when he attempts to oppen them. When you suspect a door is fake use the Vacuum on it, if it doesn't shake, it's fake. Alternatively, just check the door's position on the map. Fake Doors can be destroyed with the Fire Medal, though they'll respawn later on.

Using the Amiibo Option at the Lab there are several compatible Amiibo you can scan. Each one unlocks a special power to the Save File they are used on. If you quit the game and go back to the 'Title' Screen or shut off your 3DS, you will need to scan the Amiibo again when you begin your Save File again.

Note: Amiibo functions cannot be used in Portrait Ghost rematches in the Gallery.

Luigi:

Revives Luigi once if his HP drops to 0. Also makes furniture hiding Speedy Spirits glow blue when approached.

Mario:

Turns ALL Poison Mushrooms into Super Mushrooms that restore 25 HP.

Boo:

Shows the locations of up to 3 escaped Boos on the Map.

Toad:

Talking to Toad, even if you don't Save, restores Luigi's HP to 100.

Speedy Spirits are blue Ghosts that hide in dark rooms and in furniture and will appear when you inspect it. You will be able to suck up their 10 HP and collect the Treasure they expel if you are quick enough to capture them.
