The British TV show "Teletubbies" aired from 1997 to 2001.
Contrary to their on-screen appearance, the characters were huge: Tinky Winky was 10 feet tall, Po was 6 feet 6 inches, Laa-Laa was 6 feet 5 inches, and Dipsy was 8 feet.
To make them appear small, the show was filmed on a massive set in Wimpstone, Warwickshire, which was kept secret for a long time. However, once the show's location became known, it became an unintended tourist spot, with people trespassing to visit the "Tubbytronic Superdome."
Frustrated with the disturbances, the landowners decided to flood the set.
