The mirror room is on the 2nd floor of the castle. Once you get to the 2nd floor look to the right and you will see a door that has a star and a wooden frame thingy on the edges of it, go inside and you will be inside the mirror room. I hope i helped alot.
don't no really
You have to enter the room as Luigi. The flowers don't appear for Mario or Yoshi.
OK. To be Wario on Mario 64 DS you have to find Luigi(In the big boo world found in the courtyard)and then use him to go inside the invisible mirror on the upstairs room. Then the picture outside the mirror is Luigi but inside the mirror it is Wario. Hop inside and work your way to Chief Chilly. Defeat him and you get Wario! To be Mario, you have to defeat King Goomba in the 8-star room as Yoshi. You can get Mario very easily.
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.
hit a ? box or go to the mirror room
Look in the mirror. Your reflection should change to Luigi. Defeat King Boo and Luigi is yours.
You have to unlock Luigi and then use his invisibility power to go through the mirror, if thats what you are asking.
It is talking about wario's painting. Be Luigi to get it.
Go through the mirrors in the mirror room!
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.
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
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.
