Stairs[]
Confusing sets of pastel-colored stairs lead to almost every room. The entrances are either a geometrically shaped arches that match with the windows or a normal door. Some doors may only lead to a dead end. It is revealed in Season 2 that these stairs can lead to the Control Room, although its entrance required face-detecting scan to open it and will automatically closed once someone entering it unless something is blocking the sliding door.

There is a doll in front of a tree at the end of the room. This is the only room shown that depends on natural sunlight for the light source. The retractable roof is painted to match the forest so it is camouflaged when closed.
