As Andy and Yngvar run off Vinyl stands, paralyzed with fear for a moment as the creature bears down on him. Vinyls mind races. Y'know, you don't have your life flash before your eyes, just before death, or at least that isn't what flashed before Vinyls minds eye. What came over him was the feeling that he had a gun in his hand. Vinyl fired wildly, emptying the gun, while letting out a yell of panic.
1 bullet misses.
1 hits the right jaw.
The creature continues coming towards Vinyl even after he had emptied the gun on it. The only difference was it was it was no longer using it's legs, the creature was using pure sliding momentum. A splash and slide send the creature into Vinyl, knocking him over with it's midsection.
2 bullets had hit home.
Vinyl crawled away from the creature as it's legs twitched and abdominal muscles contorted and flexed, making the creature writhe about.
As Vinyl's hearing returned a whistling noise could be heard. It resembled steam escaping from a teapot. It was coming from the creature. Glowing liquid that looked like a mixture of milk and blue glowstick fluid leaked into the water from the creature.
Vinyl watched a man crawl away from the creature. The man wore a look of terror with tears streaking caked mud on his face. He was slowly moving away from a lot of movement. The whole scene was soundless save for that noise. It seemed very calm in a way, like a dream. Vinyl was aware he had been holding his breath.
Vinyl returned to utter chaos, sucking air into his lungs. He got to his feet and ran for his life until he found the other two panting down the tunnel, fifteen minutes later. They were crying and yelling. No one was saying anything intelligable.
