This cheat needs 3 players in order to work. Make sure somebody breaks the Smash Ball with Captain Falcon. Next, wait for a warpstar to come. Have someone get the warpstar and while this person is still zooming up or coming down ONSCREEN get ONLY the person who hasn't done anything. After you see Captain Falcon come down and everyone can move again you'll
notice that the person riding the warpstar just falls normally to the stage, for the star vanished.
