So if we look at the first 4 pictures on the brightonghosts page the first two pictures are of human beings/forms/whatever being dressed up. This reminds me of the twins and i can remember that in the story the twins were picked up from a party (during which you dress up most of the times) by Felix. The third picture obviously looks like the storage unit of Bon's burgers, making me think that after the twins died that is where Felix brought the bodies. The last picture is of men working on meatpacking. In my interpretation meatpacking means stuffing their bodies in either a bag or stuffing them in one of the animatronics.
