Gorgs, known as chubas in Huttese, were small amphibians that could be found on several planets, from the swamps of Naboo to the sewers of Tatooine. They were favored as food by many humanoid species, either dried, fricasseed, or roasted in manak leaves. In Huttese, "hot chubas" were called "hotsa chuba".
Gorgmongers, such as Tatooine's Gragra, would root a gorg pod in an amniotic-like fluid and feed it a variety of things, including funnel flowers, razor moss—or even raw sewage. Soon, the specimen would lay eggs, which then hatched into tadpoles after several days. The gorgmonger would then separate these hatchlings from the adult (as adult gorgs will devour their young) and raise them to maturity. Only then could the amphibians be sold in the bazaar or marketplace.
In 32 BBY—just out of curiosity—the Gungan Jar Jar Binks fetched a Gorg with his long tongue from Gragra's booth at the market of Mos Espa on Tatooine, and he was asked 7 wupiupi by Gragra for that. The Gorg then ended up spat out by Binks in shock at the cost, inadvertently ruining Sebulba's meal in the process and thus being beaten to a pulp by an enraged Sebulba until Anakin Skywalker broke up the fight.
There were many species of gorgs, including long-tailed, three-eyed, and four-eyed varieties. Different types of gorgs were eventually introduced to the populations of Naboo and its moon of Rori, where they evolved to become large, flesh-eating creatures. Gorgs were also known to be mutated by bio-engineers. One such mutation resulted in the successful growth of a chubafly. The chubafly was essentially a colorful gorg, but with wings that made it capable of flying.
