5x17 - Dragon Ball Z Kai

While Goku and Vegeta's fight gets underway, building energy for Majin Buu each time Goku takes damage, Gohan and Supreme Kai arrive at Majin Buu's egg, where they are confronted by Babidi and Dabura. Before the fight between them can begin, Majin Buu's egg reaches full power, as a result of Goku and Vegeta's battle.
