Hussuloofians were a race of green creatures known for their kindness and gentle nature – as well as remarkably hairy ears. They had a strong attraction to the tripeberry – a large purple berry with a strong smell that was considered to be a delicacy on the planet.
For a while their King was a Trit in the guise of their former ruler. Under the Trits reign the rule box was greatly expanded and the subjects bullied into sub-serviance. When the Trit was exposed by the Doctor the vacant position was taken on by the former King’s aide Trubbs. (DWAM: The King and the Tripeberry)
