Beat Bowser the 3rd time on the top floor of Peach's Castle. It takes 3 bombs to defeat him.
You have to either beat the final bowser or get every power starI HAVE A BETTER ANSWER!You cannot be Peach in Super Mario 64 or Super Mario 64 DS.Unless, you have Project 64 or an AR (Action Replay).Project 64 lets you play Nintendo 64 games on your computerand it comes with cheats.An AR is hard to explain.
