What if there was a race of beings where they had an organ that could super compress digested food, sort of an intestinal muscular system or something really crazy like intestines that create a localized gravitational field. Basically a person could just eat and eat and eat as much as they want and instead of turning excess into fat it would just be super compressed… at least until they "evacuate their bowels" so to speak… at which point the super compressed waste would exponentially expand upon exiting the body, making the "hyper mess" a reality.
