Setting himself up on an alien planet, Sluggman (of Sluggman Advertising Agency), used the influence of a thought-projecting helmet to plaster the city with psychic posters encouraging everyone to buy products they didn't need – notably cans of Hyper Cola (that weren't zingy or refreshing) and copies of the boyband 4Profit's latest holodisk (they couldn't sing, dance or even play their own instruments). He surrounded himself with his wealth before being exposed by Eleventh Doctor and had his helmet confiscated. Disgraced and facing a queue of angry people wanting their money back, Sluggman fled in his spaceship. (COMIC: Buy, Buy, Baby!)
