As a frustrated Oolong claims the Dragon Ball can't be found in the rubble of the destroyed castle, Bulma corrects him by finding the mystical sphere on her Dragon Radar. While Gyūmaō predicts that living in the area will be easier due to the fire being put out, Kame-Sennin apologizes for destroying the castle, only for Chi-Chi to inform the turtle hermit that the castle can simply be rebuilt.
Whilst Yamcha and Pu'ar become wary of Kame-Sennin's power, Gokū asks the turtle hermit if he can teach the young boy how to perform the Kamehameha, only for Kame-Sennin to tell Gokū it would take at least fifty years to master the technique. While Kame-Sennin denies Gyūmaō's request to live in his castle, a determined Gokū is able to perform a small Kamehameha on a nearby car after observing Kame-Sennin, much to the awe of the turtle hermit, Gyūmaō and Chi-Chi.
Kame-Sennin then discovers from Gyūmaō that Gokū is the grandson of one of his apprentices, Son Gohan, and learns from Gokū that Gohan is dead, much to Kame-Sennin's surprise. The turtle hermit then finally decides to take Gokū as his apprentice before Gokū claims he'll accept after obtaining all of the Dragon Balls. As Yamcha and Puar are amazed at Gokū's ever-growing strength, Bulma finally finds the seven star Dragon Ball, only to be deflated from finding her car to be damaged by Gokū's Kamehameha.
Gyūmaō then uses a capsule to provide Bulma, Gokū and Oolong transportation, but before they leave, Kame-Sennin reminds Bulma of the conditions they agreed to, which leads Bulma to take Oolong away from sight and force him to shape-shift into her. After one failed attempt, Oolong successfully transforms into a duplicate of Bulma, and allows Kame-Sennin to rub his face on the replica's breasts, much to the real Bulma's disgust.
Before Gokū leaves with Bulma and Oolong, Chi-Chi gets Gokū to promise to marry her when they're older. As the Dragon Team sets off to find the last Dragon Ball, Yamcha and Puar follow them closely.
