A massive, terrifying, spiked monster with sharp claws crawls through a dark, wet, and dimly lit sewer tunnel in a photorealistic style.

A terrifying, massive monster crawling through a narrow, modern underground sewer tunnel. The creature is so huge that it scrapes against the ceiling and walls as it moves, hunched and forced to contort itself. With thick, muscular limbs, sharp claws, and rough, scaled hide. Its face is bestial and eyeless, adapted to the dark, with rows of jagged teeth and a snout that drips with filth. Along its spine are long, straight, metallic or bone-like spikes impaling the meat, its horrifying form of carrying food. Long, matted, wire-like hair trails behind it on the wet sewer floor. The environment is filthy, claustrophobic, dimly lit by failing overhead lights, with dripping pipes, moldy walls, broken grates, and puddles of stagnant water. The mood is terrifying and grim.
