The Ox King on Fire Mountain

Goku, Bulma, and Oolong arrive at Fire Mountain, with Yamcha following closely behind. There, they meet the Ox King, who lives in the castle on Fire Mountain. The Ox King notices Goku's Flying Nimbus, and realizes that he must have received it from Master Roshi. He says that he sent his daughter Chi Chi to go to Master Roshi's island to borrow the Bansho Fan to put out the flames on Fire Mountain, but she never came back. The Ox King tells Goku that if he finds Chi Chi and returns with the Bansho Fan, then he can have the Dragon Ball that's inside his castle. Goku takes off and finds Chi Chi right away. After asking for directions from a dolphin, they arrive at "Kame House" on the turtle hermit's private island.
