Garr's mother and father lived on the mining planet of Excarga and were ore traders. When the Confederacy of Independent Systems tried to take control of the mines during the First Battle of Excarga, Garr's parents hid Garr while they were made prisoners, and they wasn't found until the Republic counterattacked in the Second Battle of Excarga. Garr's parents were assumed dead so Garr became an orphan and went with the Republic on the ship Candaserri to an orphanage in Bespin. Garr believed that their parents were still alive and would someday come to claim them.
Garr was Boba Fett's friend from the time when Boba was saved from Raxus Prime by a group of clone troopers and a Bothan Jedi. They met on the ship Candaserri which was taking them and other orphans to Bespin. At this time Garr was 10 years old and identified as being neither male nor female.
During their time together, to avoid suspicion, Boba lived under the name of Teff, and was assumed to be an orphan too. Both loved to explore, and their curiosity almost resulted in Boba Fett and Garr being left floating in space.
On arriving in Bespin, Boba tried to escape but was followed by Garr. Garr brought Boba's flight bag, which Boba had forgot, and while trying to persuade Boba to come back, was interrupted by Aurra Sing. Garr left Boba with Aurra, and assuming Boba was in trouble, tried to rescue Boba, telling the Jedi at the orphanage everything. This almost resulted in Boba losing his life.
