The four-foot seven-inch-tall dolls wandered around the capital during rush hour, taking in sites such as Charing Cross Tube Station, Oxford Street and Burlington Gardens.
Reminiscent of the Grady sisters from The Shining, the Victorian twins are roaming high-footfall, commuter hotpots around London as part of a weeklong marketing initiative.
The dolls have been engaging with members of the public by handing out cryptic clues for Thorpe Park’s new Derren Brown attraction in the form of pin badges, which feature a mysterious logo.
A team of tailors spent three weeks creating their white corsets and masks. Two 10-year old sisters are the stars of the stunt, which was devised by agency Taylor Herring.
Mike Vallis, divisional director of Thorpe Park Resort, said: "Following the announcement of Derren Brown curating our new 2016 attraction in October, we have had many enthusiasts try to unravel our closely guarded secret.
"Due to demand and interest in our largest investment to date, we have released our next clue, The Victorian Twins."
