super saiyan 3
When Goku shall kick majin buu ass,
Before going off kamis lockout, turn super sayan, then go up into the palace, down the stairs to the right, and in the door at the middle, and fly out the window.
Then fly to buu
When you get there and is about to fight, goku turns SUPER SAIYAN 3
Then normal, then super saiyan, then super saiyan2, and super saiyan3 (again)
WIERD (but cool) :-)
