To unlock the red "?" blocks, I think you have to be Mario. Not sure, but I think so. Anyways, go into the, well what I call the foyer, of the castle. You know, just the main entrance. Oh yeah, and you need a certain number of stars to do this. To know if you have enough stars, there will be a pillar of light shining down in the middle of the room, if you have enough. Then, have Mario look up, and there will be a painting of the sun. Once you look at it, you will appear as winged Mario in this wierd place. There will be this like pillar thing in the middle. You have to land on it, which is easiest if you ground pound. There is this big button there. You just have to ground pound it to unlock all of the blocks.





Now, to find Luigi. Go into the ghost level, and go up to the highest room. There will be doors in that room that go out to the balcony. Don't go out, but I'm just describing the room. There will be a painting of Luigi in it. Jump into it. Then, you will be in this really confusing level. I can't remember how to do it; all I remember is that you have to find King Boo and defeat him to unlock Luigi.
Reply:well i only know about how you unlock luigi. please don't criticize me this is off of memory. once you beat the first bowser and go into the basement there is a ghost follow him and kill the biggest ghost in the courtyard. once you do a small thing pops out. go to it and mario jumps in. beat the levels till you get to the...i think 4th level and you have to fight king boo. beat him using the mirror and you get a key for luigi.
