The SIDRAT is an interdimensional time machine. The exact opposite of the TARDIS, it has some unique abilities. It is larger on the outside then on the inside. Although varying in shape and size, a small version's outside would resemble a European crime ring, however the inside is about the size of a front toilet situated in a small cottage in middle England. The house is actually quite lovely, it has two cats, a greenhouse in the garden, including some rare species of orchids and an intercomm system. SIDRAT is believed to stand for Superb Intelligently Designed Radio-Active Toast.
