After his arrest by the Judoon, Androvax had acquired a disk from a Bouken pirate he met on a swamp prison planet in the Calysteral cluster. He could use to enter the Vault on Earth owned by the Alliance of Shades. (TV: The Vault of Secrets)
Strax and the Eleventh Doctor played mini-golf on Bouken. The Doctor claimed he won all three rounds. He later returned to Bouken with Amy Pond while searching for his sonic screwdriver and opened the door of the TARDIS to reveal that Strax was still there, angrily waving a golf club at him. (COMIC: Sonic Sleuth)
