How do you get Luigi in super Mario 64 for ds?

Answer 1

If you have to be able to be Mario and the ! boxes have to be red. Then go into the main room in the castle. Go threw one of the wooden doors, then follow the big boo into the boo courtyard. When you enter find the big boo, punch him when he is white, a cage should come out of him, jump into the cage. Go into the big boo mansion, and go up the stairs. Go into the room with one bookshelf and where all floor collapses if you stand on it. Go stand on the wooden ledge, with mario, and get the floating flower from the red ! box. Float up and go forward, and will be a ledge and a door, go to the ledge, land and go threw the door. Go threw the luigi painting, and you will be in a mirror room, and beatup the boo and he will give you the luigi key, then go to the room with the 'M, L, W, -' doors, and unlock luigi, i hope that helped, enjoy and good luck!
