Were you looking for:
Floor 4 assumes the appearance of a bedroom with dirty yellow walls. On the floor there are posters of KittyFazCat and Frankburt. On the wall there are two posters: one of KittyFazCat again and one of a cuter and possibly child-friendly version of The Unknown/Torture Beast. There is also a child's drawing of Jester-In-A-Box. The floor is of a dark blue color. The room has several bookshelves and a bed, with a Kitty Plush under there. There is a lamp that serves as an auxiliary light source.
Currently, only Torture Kitty and The Unknown/Torture Beast start here. The player can hide under the bed to defend himself from the Torture suits or point the flashlight on them, although this seems to provoke them sometimes, as seen with Torture Kitty in the 1st Official Trailer.
