Cimliss
From Tardis Wiki, the free Doctor Who reference
The Cimliss were a species obsessed with business, similarly to Humans, Usurians and Okk. Legion had encountered them before (NA: Lucifer Rising), possibly when they attempted to undermine the business consortia of the galaxy. (MA: The Crystal Bucephalus)
The Doctor once had Cimliss money while in a bar with Benny on Barrabas Gamma, but it jumped out of his hand and crawled into the shadows. It was still reproducing change in dark corners for weeks. This may suggest that the Cimliss had sentient money. (NA: All-Consuming Fire)
