Super Mario 64/Bowser in the Sky

To get into this stage, a player requires 70 stars and needs to have beaten Bowser in the Fire Sea.

Defeating Bowser
Get behind Bowser and grab his tail. Spin him slowly around by rotating the analog stick 360 degrees. Then toss him a little way and run up behind him and grab him again. Repeat throwing Bowser until you get close to a mine, and let him have it. The rings he stomps out are easy to jump over the closer you stand to Bowser. After you throw him into a spike twice, Bowser will break the platform into a star. Stand in the middle when he is doing this. The is a 1-up right before you enter to battle Bowser. It is right behind one of the pillars where the wind blows. Good Luck!!
