The Supply Closet is an area within Freddy Fazbear's Pizza.
It's the only room to seemingly have a security camera upon the ceiling to give an overhead look of Bonnie when within it. Since it only has a view of Bonnie when viewed, it's pretty pointless to check it at all.
Appearance
It seems to be a small room with a shelf on the wall opposite the doorway. On the shelf are labeled bottles. On the far wall, there can be seen a broom with a balled up piece of paper sitting next to it. The far wall and the floor have the same coloured tiling, except the walls tiling is larger. Next to the broom, is a mop sitting in a bucket. Near the camera there seems to be some sort of board with a wheel attached to it. On the ceiling hangs a light, which illuminated the floor below. The floor is grey and black tiled.
