After absorbing Vegito, Buu has not taken on any of his characteristics, because he hasn't digested him yet. Inside Buu, Vegito still exists. He put up a barrier during the absorption, because he let it happen on purpose. Once he dispels the barrier, Vegito splits back into Goku and Vegeta. Vegeta crushes his fusion earring, citing that once they free their absorbed friends, Buu will lose most of his power. As they journey through his innards, they find some tiny green pieces of slime. The slime starts to attack, and it completely covers Goku. Suddenly, a giant worm appears, ready to eat Goku.
