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.
