Goku reunites with Gyū-Maō's daughter, Chi-Chi, and accompanies her to Kame-Sen'nin's. The old man extinguishes the fire using the Kamehameha and finds the 6th Dragon Ball (but destroys the castle). Pilaf's soldiers steal the Dragon Balls. Yamcha helps get into the castle, but they are trapped. With the 7 Dragon Balls gathered, Pilaf summons Shenlong and prepares to wish for world domination, but Oolong interrupts him by wishing for a girl's panties. Enraged, Pilaf traps everyone. Goku sees the full moon and transforms into the Great Ape, destroying the castle. Yamcha and Pu'ar cut off his tail, and Goku reverts to being a child. Goku separates from his friends to train with Kame-Sen'nin (who demands he bring back a girl to do the housework).
