the Eleventh Doctor's TARDIS. It is a sentient time and space machine, meaning that it can travel anywhere in time and space. From the outside, it appears to be a blue police public call box, due to its chameleon circuit being broken. It appears to be bigger on the inside than the outside, due to it being dimensionally transcedental. It is currently owned by the Eleventh Doctor, and it has had two interiors to it.
