The people of earth come back to life, including the Z Fighters and their friends. Goku gets into position to create the Spirit Bomb, and with the help of King Kai, Vegeta speaks to the entire population of earth. He tells them what's going on, and that to defeat Buu, they need to raise their hands up and offer their energy. Only Goku and Vegeta's family and friends comply. No one else is willing to listen to a mysterious voice from the sky. Vegeta repeatedly pleads with the earthlings, but to no avail. While this is going on, old Buu is buying them time by fighting Kid Buu, but it's not going well. Goku hasn't gathered nearly enough energy to destroy Buu.
