Many of the people I know, have been wondering how to go through the adventure as Luigi. Well, what you have to do is, get all the stars (120) and beat the final level. After you beat it, it will look the same, but in the movie the little star Mario keeps goes away, and finds Luigi! Then you replay the game as Luigi but in the cosmic commets, the shadow luigi is much harder.

I know it’s Mario in Luigi’s clothes, it’s a cool picture. Do you like the blog? I treat it more like a website actually.
