A terrifying swamp monster rises from the mist under a pale full moon. Its skin is covered in moss, mud, and algae, dripping with dirty water. Glowing yellow eyes pierce through the darkness, and its long twisted claws stretch above the murky surface. Behind it, dead trees and tangled vines form a haunting backdrop, with eerie fireflies floating in the fog. The air feels humid and heavy, filled with an unsettling sense of dread — a perfect creature for Halloween night. Style: dark realism, cinematic lighting, moonlit horror atmosphere., #Halloween2025
