Now that Vegeta's gone, there's only the small matter of reviving everyone killed in the battle. A task made somewhat harder by Piccolo (and by extension Kami) being dead too. Thankfully (?) Mr. Popo arrives to tell them about Namek, give them a space ship and generally freak everyone out.
That sorted, all that's left is for Gohan, Krillian and Bulma to get going. But Chi-Chi has other ideas.
