The Gelboians are the people of planet Gelbo.
The Gelboians were menaced by the giant catfish monster Zoonama, who threatened to cause a giant earthquake if he did not get what he wanted. One of the Black-Star Dragon Balls landed on Gelbo forcing Goku, Pan and Trunks to help the Gelboians in return for it. It was later revealed that Zoonama could only predict earthquakes.
