Jaccoba was a young Wookiee who lived on the planet Kashyyyk during the Clone Wars. He was the son of Tarkov. While on a hunt with his father, Jaccoba accidentally threw his spear at a large wall of shrubbery, which made a strange metallic sound. His father pulled down the wall of shrubbery to investigate, revealing a Separatist landing craft. Tarkov grabbed Jaccoba, and took him to the safety of a nearby tree.
