A nursery ring served as a place for the rearing of young Wookiees. At these nursery rings, males participated in boisterous play, which cultivated fearless and reckless combat techniques. A particular nursery ring existed within the city known as Rwookrrorro. Prior to her marriage to Chewbacca, Mallatobuck was employed at a different ring located in a village in proximity to Rwookrrorro.
