The Kamehameha Wave

Master Roshi agrees to let Goku borrow the Bansho fan, but when he goes to retrieve it, he remembers that he spilled juice on it and threw it out. He decides to put out the fire himself. When they arrive back at Fire Mountain, Master Roshi uses his famous Kamehame-Ha to blow out the flames. The wave puts out the fire, but it also destroys the entire mountain. With the Dragon Radar, Bulma is able to search through the rubble and find the Seven-Star Ball (Qi Xing Qui). Goku asks Master Roshi if he can learn the Kamehame-Ha, but is disappointed to find out that it took the turtle hermit 50 years to learn it. He tries it anyway, and is miraculously able to do it on the first try.
