TARDIS storeroom

The Doctor's TARDIS had various storerooms. These included Storeroom 89, 90, 104 (PROSE: Keeping up with the Joneses) and a box-room. (COMIC: Exodus)

One storeroom contained a deflatable cushion-craft which the Doctor had invented. The First Doctor used this craft to traverse a swamp on Corbo. (PROSE: The Devil-Birds of Corbo)
