One Piece - episode 100 - 09 Feb, 2002

Still trekking through the Alabasta desert, the crew beats up a giant desert scorpion for lunch, while Vivi tells Nami about her past and her friendship with Kohza. When his village faced a drought, he appealed the king for help, and Cobra allowed the villagers to stay in the capital. He and Vivi were initially not on good terms, getting into a fight when they first met, but Vivi became vice-leader of the Sand Sand Clan, and Kohza's group risked their lives to save her from kidnappers. Kohza then left with his father to establish a new town called Yuba. (Source: Wikipedia) Alabasta saga: Alabasta arc: (9/39)
