Dragon Ball Episode 3
The Nimbus Cloud of Roshi
On their way to the sea, Goku and Bulma run into a giant beast that wants to eat the turtle. Goku makes short work of him, and they continue on their way. When they arrive at the shore, the turtle tells them to wait for him. When he comes back, a man is riding on his back. That man is the turtle hermit: Master Roshi, and as a reward for helping his sea turtle, he gives Goku a flying cloud called the Flying Nimbus. Master Roshi himself cannot ride the cloud, because only good and pure people can. Bulma can’t ride it either, but Goku can, because he has a good heart. Roshi also gives Bulma the Three-Star Ball (San Xing Qui), not knowing what it is. When Master Roshi returns to his island, he finds Pilaf and his two henchmen searching his house for the Dragon Ball. After he tells them that he gave it away, the three leave his island.
