After Kid Buu is killed, Goku, Vegeta, Hercule, Dende, and Good Buu all return to Earth. Six months later Goku and the others wish for the Earthling's memory of Majin Buu to be erased and he's free to go get into all sorts of shenanigans out in the city. He wins a fight and gets money for ice cream and then helps Bulma carry her grocery bags home. Majin Buu and Bulma thwart a jewelry store heist who are really the guys he "accidentally" beat up the first time. Saiyaman and Saiyagirl, his new sidekick/girlfriend, arrive just in time (too late). Later, Goku, Trunks, and Goten are in the hot tub and the boys fuse and attack Super Saiyan Goku in a playful fight. The tub breaks and the two are left standing in front of their friends naked and Goku laughs while Chichi runs after Gotenks to spank him just like in the good old days.
