Jigglers are a large rotund species that were introduced to Planet Earth.
The Jiggler species debuted in the original Dragon Ball series with Buyon, a large pink Jiggler kept by General White in the secret floor of his Muscle Tower. In Age 750, General White dropped the Saiyan survivor Goku and traitorous Android 8 into Buyon's lair within Muscle Tower in order to eliminate them. Buyon proved to be a difficult opponent for the young Saiyan, able to take a direct hit from Goku's Kamehameha without suffering any damage. However Goku eventually discovered Buyon's vulnerability to cold temperatures and used it to defeat him by breaking a hole in the tower's wall allowing the cold air from outside the tower to rush into Buyon's Lair, freezing Buyon solid allowing Goku to shatter him with a single punch, killing him.
The Jigglers are revealed to be from a different planet in the computer game Dragon Ball Online. The Dragon Ball Online timeline reveals that during the Galactic Frieza Army's attack on Earth in Age 820 they brought many Jigglers along with them to counter the martial artists' basic attacks, but are defeated by Goten and Trunks using swords.
By the time of Age 1000, Jigglers had become common on Earth, due to having been introduced to the planet by the Frieza Force. Some of these Jigglers have even adapted to cold temperatures, growing a layer of fur on their bodies.
- Buyon – The Jiggler kept by General White in the Muscle Tower.
- Gakin (ガキン) - A green palette-swap of Buyon that appears in Dragon Ball 3: Gokuden.
- The species is unnamed in the original Japanese manga and anime of Dragon Ball, with "Jiggler" coming from the Viz translation of the manga. In Dragon Ball Online, Jigglers are simply referred to as "Buyon-type aliens" or "Buyons".
- The Jiggler Buyon is the first alien lifeform (not native to Earth) that the Saiyan Goku ever fought. It is never explained how the Red Ribbon Army acquired such a creature or how Buyon came to Earth. Ironically, Buyon's appearance in the Red Ribbon Army Saga predate the first appearance of Namekians in the King Piccolo Saga in the manga and anime. However it should be noted that Namekians have been on Earth far longer as the Nameless Namekian, Kami, and King Piccolo were living on Earth long before Goku (it is unknown when Buyon actually came to Earth).
