Sirrakuk was the younger sister of Lowbacca. She shaved distinctive patches into her fur and loved to fly starships. Sirra completed her rite of passage (which she was hesitant to do because of the supposed death of her friend Raaba while doing hers) during a fight with a Nightsister in the lower levels of Kashyyyk. Both Sirra and the Nightsister were swallowed by a syren plant, but Sirra escaped and grabbed a handful of fibers on her way out.
