They are part of the sky texture in Mystic Mansion and they can be seen outside of the rooms. In Hang Castle they have more face texture enhancements than Mystic Mansion does. They cannot be touched in Mystic Mansion because they don't have collision. In Hang Castle, some have collision and some others don't. They have different body textures in the two different stages. When the player tries to go to them in some positions, they go black when trying to touch it. They are used to make scary towers and used in Missions as an area.
