As Son Goku and Bulma take the turtle to the ocean they are attacked by a bear, who Goku defeats. Meanwhile Shuu and Mai inform Pilaf that there was no dragon ball at Skull Valley. The three of them go to a remote island in the Emerald Sea to get a dragon ball from Roshi, the turtle hermit, but they can't find it. Goku and Bulma meet Roshi, who is the master of the turtle they helped, and in gratitude Roshi gives them the dragon ball and his flying nimbus cloud.
