Majin Buu and Mr. Satan are still hanging around with each other, and Goten and Trunks fuse into Super Saiyan Gotenks. Instead of fighting Buu, Gotenks flies around the Earth eight times. By the time Piccolo talks him into fighting Buu, his fusion wears off and Goten and Trunks are forced to leave.
Buu leaves to destroy more people, but finds an injured puppy dog. Buu is disappointed that it doesn't get scared and run away from him, so he heals its broken leg. But the puppy is not afraid of Buu, it likes him for healing him and so now Buu is friends with Mr. Satan and the puppy (whom Buu calls "Bee"). Meanwhile, two deranged gunmen named Smitty and Van Zant go around killing innocent people.
Mr. Satan goes to get Bee dog food, and decides to give Buu a second chance. He asks Buu why he kills people and destroys cities. Buu says Bibidi and Babidi told him. He asks if killing innocent people is wrong. When Mr. Satan tells him that it is, Buu immediately decides not to hurt people or destroy cities anymore, much to Mr. Satan's delight. But unfortunately, Smitty and Van Zant decide to go to Buu's house to kill Buu themselves (so they can kill people instead). Upon their arrival, Van Zant shoots Bee.
