Porunga to Futatsu no Negai) is the eighth episode of the Kid Buu Saga and the two hundred eighty-third overall episode in the original dubbed and the uncut Dragon Ball Z series. The episode first aired on November 15, 1995. Its original American air date was March 25, 2003.
The episode begins with the fat Majin Buu and Mr. Satan fighting Kid Buu. Vegeta is mad at Goku because he was unable to power up. Goku tells him that he learned to be a Super Saiyan 3 when he was dead and he did not know that his body uses twice as much energy while alive.
Vegeta tells Dende and Kibito Kai to go to New Namek and wish Earth back. Old Kai does not want to, but Dende coaxes him into going there. Goku asks why he wants to wish Earth back now. Then Vegeta asks how many times Goku has saved the Earth. Goku says that it has been at least half a dozen, to which Vegeta replies that it is time for the Earth to save itself for once.
Meanwhile, Dende and the others make it to New Planet Namek. When Dende reaches there, he receives a warm welcome and learns that the Namekians have already gathered the Dragon Balls. Then Dende asks Vegeta for the wishes, to which Vegeta replies: bring back Earth and all its inhabitants, excluding of the most evil ones. Dende makes the wishes after a minor setback.
Back on the planet, Majin Buu and Kid Buu are fighting. Mr. Satan is in the middle trying to help the fat Buu, always getting kicked off quickly. Meanwhile, all the good people who died after the destruction in the 25th World Martial Arts Tournament are wished back, including Old Kai, Vegeta, Gohan, Piccolo, Krillin, Goten, Trunks, Bulma, and Chi-Chi. Goku asks Vegeta what his plan is and Vegeta reveals that his plan is to revive the citizens and create a Spirit Bomb using the energy from the Earth to destroy Kid Buu.
