Gomainer

 Seven days have passed since launch, and Bulma is bored out of her mind.

 So she spends her days complaining, making a mess, and sexually frustrating Kuririn by running around in her panties. 

Gohan and Kuririn pass the time by "Image Training", which is a sort of meditative trance they do so they can practice their skills... I think?

Meanwhile, Muten Roshi has retaken his role as Son Gokus teacher.

Later a nurse comes in to chew them out for training, so Roshi grabs her butt. (Logical.) This earns him the nickname Grandpa Glad-hands, which he isnt too thrilled about.

(Why isnt Goku Image Training too? Wouldnt that make more sense than hurting his body?)

On the roof of W. Kong Hospital, Chichi watches the sky, wishing Gohan would write to her.

(A mother who loves her son, guys. Such a bitch.)

Aboard Kami-samas spaceship, 20-odd days away from Planet Namek, Bulma wonders aloud about Vegeta. Where could he be going to have his injuries treated? She recalls Raditz mentioning that the Saiyans sold planets to other aliens. Perhaps one of those aliens planets...?

 Out of nowhere, our heroes are attacked by a star fleet!!

 Luckily, Kamis ship is equipped with self defense mechanisms...

 ... which far outstrip the power of the space cruisers!

 But just as our heroes escape danger... another ship exactly like their own is headed for a collision course with Kamis ship!

 It turns out, however, to have been an entirely different space ship entirely, which used a reflective, mirror-like surface to trap potential enemy shuttles.

 Aboard the space station, our heroes search for life, and in the process escape many booby-traps.

 Or it finds them...

A room full of armed children coming out of every corner, with their weapons drawn on our heroes. What is going on with this space station...??? 

Elsewhere, deep in space, Vegeta swears his revenge on Kakarotto!!
