Sungwas were enormous scavengers that traveled in packs, akin to doglike creatures, and were native to the bog moon of Bogden. These beasts, which resembled a terrifying blend of wolf and weasel, were four-legged animals with yellow hides covered in golden fur and a set of red eyes.
A group of sungwas made their home in an abandoned freighter that was stranded in one of the moon's swamps, which then served as a base for the pirate known as Gir Kybo Ren-Cha. Ren-Cha, after imprisoning Gerin Toda, the daughter of Lord Malameu Toda, on the starship, tried to use the sungwa pack to prevent her from escaping her confinement. Despite this, Toda, with assistance from Jann Tosh and C-3PO, managed to fend off the sungwas. Jessica Meade and R2-D2 accompanied them, having been dispatched by King Mon Julpa of Tammuz-an to free Toda. Meanwhile, R2-D2 lured the pack away and cleverly directed them to attack Ren-Cha, who was chasing the intruders through the decaying ship's interior.
The first appearance of Sungwas was in the episode titled "The Revenge of Kybo Ren," which was the eighth episode of the animated series Star Wars: Droids: The Adventures of R2-D2 and C-3PO. It was initially broadcast on October 26, 1985.
