Where is the ghost level where you get lugai in super Mario ds?

Answer 1

to get luigi in Mario DS, you have to first defeat the first bowser then go down through the wooden doors and go right down a corridor which will bring you out into a courtyard, theres many boos around here to get a star kill a certain few boos, but to get the ghost level you kill the big boo with Mario (Yoshi cant do it) and there will be a cage go in it, once you've done that do the first star then (as Mario) i think the second star go as high as u can until theres a U turn room with a trap door to make u fall down go the bottom right of the room and there is a RED block that will make Mario inflate go up loads and ul see another door go through there and there will be the luigi painting
