This is a crater hellion.
This is a bobbit worm. The bobbit worm can grow up to 10 feet long. That’s huge. It hides in the sand, waiting for prey to pass over. Then it shoots out and snatches them out of the water, sometimes biting them in half. It can also inject them with a toxin, which helps it digest them. There are videos out there of these creatures hunting things. They’re freaky. I’m not posting a link because I’d have to go look for them myself, and I’ve already seen them.
Now imagine a bobbit worm, but make it even bigger. Now light it on fire. Now you have a crater hellion.
