TARDIS stands for Time And Relative Dimension In Space. It looks just like a wooden Police Telephone Box from the 1950s on the outside, but is of infinite proportions on the inside. This incredible time machine is piloted by the Doctor, a mysterious Time Lord, and is able to transport him anywhere through time and space, disappearing in one place and reappearing somewhere new. Amy Pond waited 14 years for her chance to travel with the Doctor, after meeting him when she was seven years old. Despite her small-town roots, Amy takes everything in stride and quickly becomes the Doctor's best friend.
