Mimbanite

Mimbanites are one of the native races of the planet Mimban. Unwilling or unable to retreat to caves deep in the swamplands like their cousins, the Coway, when the Galactic Empire set up their mining operations, Mimbanites were reduced to scavenging garbage heaps and begging for alcohol. This once proud race was held in contempt by the Imperial troops and miners.

Like the Coway, Mimbanites are humanoids with short fur, but they are smaller and less robust. Their fur is green rather than gray, hence the derogatory nickname Greenies.
