Synopsis

Taabou's out on a space patrol when he lands on an alien world and runs into the Scorpio Brothers. Poyo, another alien, saves him—turns out Poyo's been trying to protect the planet from those guys. Taabou decides to help, and the two of them take off together. They head toward a black hole that acts as a wormhole, which takes them to an underwater planet. There's a palace there that looks straight out of the folktale Urashima Tarou. A dragon god shows up and asks them to rescue a princess, so Taabou and Poyo blast off to the next planet to do it.
