Quockran

The Quockrans were the only sentient race native to the planet Quockra IV. The average Quockran was an enormous, black-skinned slug which lived below the surface of the planet during the day, emerging at night as the desert cools. It was the Quockrans who built the strange droids which populate the surface of their planet, creating them to interact with offworlders. The Quockrans despise non-Quockrans, although they were in no way violent about it. They just dislike alien creatures.
