Sur une île de Tortue Géniale

As General Blue's men recover the scouts, Goku makes it to Roshi's island. Roshi offers the submarine (which Krillin and Launch are using) in exchange for Bulma's microband. Meanwhile Commander Red orders General Blue to take action. Roshi attempts to use the microband for some indecent mischief, and Launch and Krillin return. While planning to find the dragon ball, Krillin mentions something about Pirates' Treasure and Master Roshi tells its tale. After Goku, Bulma and Krillin leave, a RR scout spies the island. (Source: Wikipedia)
