This is a cool glitch in Super Mario 64 DS (maybe Super Mario 64 too but dunno). So first, goto Snowman's Land. Choose the "5 Silver Stars" star. So first, get 5 silver stars. Now a real star will appear. Don't get it. Instead, go to the igloo and go in the then go out. The silver stars will be back again, but you'll still have 5 and the real star will still be there. So now get another silver star, and you'll get it. But now the music will be quieter and everything should be "frozen". Now you can move around with the star above your head. Nothing will do anything, you'll just go right through it. Enemies and everyhing (not terrain of course). It will be because it still thinks you're getting the star, but it can't register more than 5. You can't press Start (like Ditto glitch), so the only way to get out is to keep falling on the water that hurts you. Using this you can do some pretty cool stuff, especially seeing killer closeups of the ice dude (the dude that you fight on the ice platform). A pretty easy glitch really, but most players (and sensible ones) just go right for the star when it appears. Cool glitch.
