Surviving on the streets of Nar Shaddaa by performing tricks and eating rats, Gargonn lost the right side of his head after being attacked by a wandrella on Circarpous V. Developing a small entertainment business, he eventually fell into the trade of endangered and exotic plants and animals.
During their mission to Nar Shaddaa to investigate the smuggling of akk dogs, Jedi Masters Mace Windu and Depa Billaba questioned him, and determined him to be the ring leader. After a brief mix up with mutated akk dogs, the Jedi escaped, though lost Gargonn. The two Jedi speculated that Gargonn's head would heal within one hundred years.
