After Beerus destroyed the planet, Beerus is reminded of his dream and tells Whis about the Super Saiyan God and they go back to Beerus' planet to talk about it while they eat.
On their way back to Beerus' planet, Beerus is still trying to remember the figure from his dream and gets hungry for thinking so much. Whis says that he has a special surprise for the two in the fridge. While thinking about for a while, Beerus questions Whis' speed, to which Whis claims he is the fastest being in the universe. When they get there, the Oracle Fish was summoned and remembered the Super Saiyan God for Beerus.
