Super Mario 64 DS Glitches

Complete Eye to Eye in the Secret Room without Luigi
You need to be either Mario or Wario with Mario's cap on for this glitch to work. Obviously, you have to go to Big Boo's Haunt and go to the attic. Position yourself so that you are right next to the Boo painting (where you fight Big Mr. I) and wait for a Boo to come out. Simply defeat it and it will release a Power Star. Oddly enough, this is the same Power Star held by Big Mr. I inside the room, and the glitch might not work, so the requirements are unknown.
