1994 film

An adaptation by V-Jump Festa of a one shot manga by Akira Toriyama.

Three weeks have gone by since the alien spaceship crash landed on the Graviton City spire, and since then the aliens have been hard at work converting their ship to a pleasure district, hoping to make friends with the humans!… Not. Perpetually late and continually over-eating A-ko, spacy and cheerful C-ko, and brilliant and bold B-ko are about to enter summer break from school, and it just so happens the alien ship is open for business. When a free meal turns into a sob story about how the aliens just want to go home, will it be A-ko or B-ko who can get the ship into orbit again?

Not paying attention to his job, a young demon allows the evil cleansing machine to overflow and explode, turning the young demon into the infamous monster Janemba. Goku and Vegeta make solo attempts to defeat the monster, but realize their only option is fusion.
