It's a big snake-like thing make or rocks. Don't get too close.

Initially generated with DALL-E 3 via Bing Image Creator, using prompt: Enormous snake made of rocks towering over jungle, fantasy.

Used Juggernaut XL to upscale and enhance the image and change the style.

To my utter surprise, this guy got 1st place in the Earth category of the Elemental Extravaganza Contest! As this might get this image slightly more attention than usual (which is next to nothing) I posted an article about its creation process.
