How do you unlock luigi and wario?

Scroll up. I have answered this question for somebody else.

Luigi: Go to Big Boo's Haunt ( which you should know where it is, go to the wooden doors in the lobby and follow the boo), if you have past the first level in that area, go up the steps then go to the furthest door on the right, ( you should be doing this as mario) , hit the ? Block, then float yourself up to a secret door above where you just were, then enter the painting with Luigi. Turn the sound up, then listen for Big Boo's laughs, enter the doors that will lead to him, then when you get to him, backflip then ground pound on top of him. Repeat 3 times, then, grab the key, you will then go back to the place where all those boos are,go to the room where the others are locked up, go get Luigi, then go to the mirror (for everyone else, STOP ASKING THIS QUESTION, it's driving me nuts, sorry about that, well, go there, grab a power flower, go through the mirror, and enter the door on the other side grab the star, ( This is just a secret star) go back then enter the painting of Wario, go down the slide, across the gorge, follow the path go right, then right again, across another gorge, the go up those moving snow blocks, then enter the hole at the top, defeat Chief Chilly by knocking him over like a bully at Lethal Lava Land 3 times grab the key and then return back to the place where th elocked doors are , enter wario's door, then now you know how to unlock the chraracters.
P.S I never lie.
