The Nimbus Cloud of Roshi

On the way to the beach with the Turtle, Goku and Bulma encounter a Bear Thief who would like to eat the Turtle. Goku refuses him and has his first real battle, easily defeating the bear in seconds. When they get to the beach shortly afterward Goku bids goodbye to Turtle, and sets him into the sea. Turtle tells them to wait, he has a gift to give to them. Turtle returns with his master, the Turtle Hermit, Master Roshi, and introduces him to Bulma and Goku. Master Roshi wants to reward Goku with a gift, so he gives him the magical Flying Nimbus, a cloud that can fly anywhere, but can only be ridden by those of pure heart. Master Roshi tries to demonstrate, but falls through it. Goku, of course, rides it with ease.

Meanwhile, Emperor Pilaf's next target is Master Roshi's house, because apparently the old master has a Dragon Ball in the vicinity. He furiously tries to unlock the door with a key, but it does not work. Mai bluntly points out that there's a window open already.

At the beach, Bulma also demands a prize from Roshi, despite Turtle's comments that Goku was the only one who helped him. She immediately notices the Dragon Ball hanging from Master Roshi's neck, and asks for it. Master Roshi asks her to show him her body with only undergarments in return, and she screams at him instead. After weighing the matter, Bulma consents to doing so. However, unknown to her, Goku had removed her underwear earlier that morning, and she inadvertently exposes her naked body to Master Roshi. Thoroughly satisfied, Roshi surrenders the Dragon Ball, oblivious to its real power, and Bulma happily scores her fourth Dragon Ball (still unaware of what she had truly done to earn it).

Goku and Bulma make it back to get the Capsule House near Skull Valley when Bulma finds out her panties were not on. Goku confesses to taking them off her and she furiously shoots at him with a MAC-11. Afterward, Bulma attempts to ride the Flying Nimbus only to be rejected, leaving her to stick with her capsules.

Back at Kame House Emperor Pilaf is threatening an Alligator with a switchblade, When Roshi shows up only to find that Emperor Pilaf and the others have ripped it apart trying to find the Dragon Ball. Emperor Pilaf shouts at Master Roshi, asking him where his Dragon Ball is. Master Roshi shrugs, saying he gave it to the pretty girl who was just at the beach. Emperor Pilaf goes insane, and they hop back into their ship, asking Master Roshi to shove it off the beach for them. He does, but not before ripping a hole in the bottom which eventually causes their ship to sink to the bottom of the sea.
