What are the barnacles doing on Mahogany's chest in Midnight Meat Train? - barnacles midnight meat train

There is a scene in the train of flesh midnight, when the murderer cut his chest bumps barnacles in the mirror and then submit them in pots in your kit. The shocks are not explained. We thought that might get the main character of the same burrs at the end of the film, but not really showing. Is it bad to write full-screen, or is there a deeper meaning?
