Buu Against Buu

Buu Fights the evil Buu to see who will win, but in the end, the good Buu shoots out a ray to turn the evil Buu into a cookie, but the evil Buu blew it back in his face and the good Buu turned into a cookie instead. The evil Buu eats the good Buu and gains his power to become a new Buu. Afterwards, he wants a good challenge and remembers being promised that he would have a good fight with Goten and Trunks, so he decides to pay them an early unexpected visit.
