After a long search, Goku and Chi-Chi find Master Roshi’s island and request the Bansho Fan. Unfortunately, Master Roshi threw it out after spilling soup on it. He will still help, though, if Bulma goes on a date with him. Later at Fire Mountain, Master Roshi gathers the needed strength to unleash the Kamehameha Wave. This tactic works a little too well – completely destroying the mountain, but things ultimately work out for just about every featured party.
