STARDIS

The Stardis was a teleport vessel based on legends of the Doctor's TARDIS, owned by the con artist Banto Zame who posed as the Doctor with his companion Sally-Anne Stubbins. It appeared in the shape of an Earth portaloo due to a historical inaccuracy based on the TARDIS' police box exterior. The dematerialization sounded like a toilet flushing. (AUDIO: The One Doctor)
