TARDIS storeroom
From Tardis Wiki, the free Doctor Who reference
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) He also had a black box in a storeroom which, when opened, let out a flash of blue light and the smell of ozone. He once used this box to incapacitate the Cyclops Fo. (PROSE: The Playthings of Fo) He also kept his atmospheric density jackets in one of the storerooms. (PROSE: Valley of Dragons)
