Krunch, a Wookiee, held the position of chief mechanic in Bolabo Hujaan's establishment, specifically Bolabo's Garage located on Byblos. Their initial encounter occurred while collaborating on a smuggler's starship, and Krunch remained with Bolabo after Bolabo gained his freedom. Bolabo stated that the Wookiee's name, Krunch, was derived from the sound made by customers who failed to settle their repair bills.
Throughout the duration of the Galactic Civil War, Krunch seldom ventured outside the Garage due to his apprehension that Imperial troops might subject him to enslavement.
Due to Krunch's remarkable mechanical abilities, which enabled him to perform extraordinary feats on practically any starship, the Garage's clientele consistently expressed satisfaction.
