Warehouse is an area accessible from the Nail World, via the Red Nail Passage. To get into this area, you need to pass directly through the Window Room (going right-to-left). After exiting it, search for three bloody nails outside of the nail path. They will transport you to the Warehouse's outside area.
Features
Outside Area

Inside Area

There are four floors in the warehouse that you can access through the stairways. At the top floor there is a white passage and you'll see again the rotating triangle. By interacting with it, you'll get the Polygon Effect. Also, on the top floor, after the white door, there is a room with stairs, By going down the stairs and passing some rooms, you can find a four-leaf-clover. BY interacting with it, you'll be transported to Grass World.
