Once you get in the castle, head through the door in front of you if you have the key from Bowser in the basement. Go upstears through the door. Go to your right & head through the door. If you have Luigi then you can get the flower on the column & head through the miror. You can choose 3 ways: Jump in Wario's picture, Head through the door, or head back. A star is in the door in the miror.
don't no really
hit a ? box or go to the mirror room
It is talking about wario's painting. Be Luigi to get it.
Go through the mirrors in the mirror room!
If you mean the mirror room where you unlock Luigi (in Big Boo's Haunt) when you fall to the room, just go forward and touch the mirror with Mario, then wait. You'll have to battle King Boo to unlock him.
You have to unlock Luigi and then use his invisibility power to go through the mirror, if thats what you are asking.
You get luigi and you get the flower on the pillar and then you exit the reflection of the door in the mirror
there is no mirror key. using luigi go to the mirror room, grab a power flower, and you can go thru the mirror no u cant it doesnt work
You partially answered your own question there. In Super Mario 64 DS (not the original N64 game), Luigi will notice flowers in the mirror room after the ? switch is activated. By using one he will be able to pass through the mirror.
Because there was no room in the game for him so Mario fired him..
Well he white room is only in super mario 64 ds, but you need luigi to get to it. It is located on the second floor in the room where the mirrors are. Make luigi get a power flower on one of the pedestals, then walk through the mirror. Then enter the door leading to the white room where a star is located. Hope this helped:)
The one in the mirror room on the floor with wet-dry world in it. The mirror shows a cool, cool mountain painting that isn't actually there. The mirror room is the one with the five pillars.
