Only Goku, Bulma and Kuririn stand between the Red Ribbon Army and the seven Dragon Balls which can grant any wish in the world! Using a submarine loaned by Kame-Sen'nin, the heroic trio explores a pirate's undersea cave in search of the next Dragon Ball, but gun-toting bad guys are on their tail! Now they must face not only perilous pirate traps but the sinister General Blue, a martial artist with powers even Goku doesn't have! Can they escape the cave alive? As the battle continues, Goku and General Blue go to Penguin Village, the home of the weird scientist Dr. Slump and one of the strangest places on Earth!
The sea-bottom cave that they got lost in searching for the dragonballs turned out to be a secret pirate base. Goku and co. somehow manage to escape from both the pirates' trap and General Blue's evil hand to obtain a dragonball.
Having returned safely to Kame House, Goku and co. have their dragonballs stolen by General Blue, who they thought had died in the cave.
After he had retrieved his dragonballs with the help of the citizens of Penguin Village, Goku headed for the Karin Holy Land in search of the next ball. There lived the father and son Bora and Upa, who protect the holy land.
