Celestial Omnibus

Iris Wildthyme's TARDIS was quite unusual. It was slightly smaller on the inside, than on the outside. (Other TARDISes was often bigger on the inside than on the outside.)

For most of the time Iris' TARDIS looked like a big red bouble decker bus, usually number 22 to Putney.

The TARDIS had a small kitchenette in the back, a shower and a wardrobe upstairs. The controls were at the dashboard.
