Brubbs were a very social people, living in large communal groups called habas. Most habas were extended family groups which raised children communally and operated some specialized business together, such as a farm, a mine, or even a vacation resort. Certain "university" habas, however, were drawn from the best and brightest of many habas. These groups had technology approaching galactic standard, especially in the areas of solar and wind power. According to Obo Rin's Catalog of Intelligent Life in the Galaxy, it was one of these university habas that first made contact with the outside galaxy, by beaming radio signals which eventually came to the attention of the Galactic Empire. Some evidence exists of earlier Brubb contact with other inhabited worlds, however. In 32 BBY, a cantina in Mos Espa on Tatooine was known as "The Blue Brubb".
Each haba was governed by its ten oldest Brubbs. As female Brubbs had a lower life expectancy, due to the stress of egg-laying, the leaders were almost always male. At the same time that the Brubbs were dealing with first contact with aliens, many female Brubbs were arguing for an equal share in haba leadership, and protesting by refusing to lay eggs.
Since Baros was a high-gravity world with few natural resources and low-tech natives, the Brubbs did not see much interstellar trade. Their main commodities were the Brubbs themselves—their strength and toughness made them prized mercenaries and laborers. Jabba the Hutt employed some Brubbs as guards on Khetanna, his sail barge. Other Brubbs, due to their sociable nature and interesting appearance, became "ornamental" beings hired as retainers for wealthy Core Worlders.
