Dragon Ball Z Episode 287 SUB at Gogoanime

Synopsis: The Supreme Kai brings Dende back to the world of the Kais. Dende heals Vegeta and Goku. Hercule finds the body of old Buu, and asks Dende to heal him. Vegeta won't let him, and plans to destroy him. He says it is too dangerous for any form of Majin Buu to exist, but Hercule continues to plead with him. Goku takes Hercule's side, explaining to Vegeta that it was old Buu who saved Vegeta's life right before Goku threw the Spirit Bomb. Vegeta reluctantly agrees, and Majin Buu is healed. Supreme Kai takes them all back to Dende's lookout, where they reunite with friends and family. Goku tells his family that Elder Kai gave him his life, so he can stay on earth for good. Four months later, they use their remaining wish with Shenron, asking him to erase the memory of Majin Buu from the mind of everyone on earth, so that the good Buu can assimilate into society. Life finally returns to normal on earth.
