Bulma, Yamcha, Oolong, and Puar are able to escape. Pilaf, Mai, and Shu board an airplane and start attacking Goku. They are able to bring him down temporarily, but Goku recovers and destroys their plane. He then picks up Bulma and prepares to eat her. Remembering that his tail is his weak point, Yamcha grabs Goku's tail, and Puar changes into a giant pair of scissors and cuts it off. Goku regresses back to his normal self; naked, and sleeps until morning. When he wakes up, he is shocked to find that his tail is missing and that he is naked, and remembers nothing about his transformation and rampage. He borrows Oolong's pants and finds his Power Pole in the rubble, but finds it hard to balance without his tail. Yamcha and Bulma decide to go back to West City together, with Puar and Oolong tagging along. Goku decides to go find the turtle hermit to get the training he was promised. Bulma gives Goku the Dragon Radar so he can find the Four-Star Ball when the Dragon Balls reappear.
