The Observer is a creature made by Trevor Henderson. Based on the detail provided by the photo, it appears to possess an uncanny appearance, owing to its pale face, wide, lopsided eyes and gaping mouth. It was first discovered when an unknown passerby spotted it fiddling with a couple of locks that prevented entrance into a room. The creature may have intended to break into the room, but the reason for that is unknown. Another photo that possibly depicts the same creature exists, although this time it is located in a subway.
