Short story but pretty gory. Definitely not for the young.
It Wakes
Up in the mountains behind West City, a team of builders was hard at work building a new scenic road through the mountain face with a thick forest on both sides. A tunnel was being excavated near the top to make a pathway through the mountain. Dynamite was being used to blow away the rocks and the noise was intense. So intense... That it had disturbed something sinister in the forest.
Crewman 1: "Fire in the hole!"
Crewman 2: "Fire in the hole!"
A sudden boom echoed across the land as a set of dynamite was set off. Once the smoke cleared, the crewmen stepped forward to remove the debris.
Chief Builder: "At this rate, we'll be ahead of schedule."
While some removed the rocks with the cranes and bulldozers, others were removing the rocks by hand. One man was standing near the forest with his back turned as he nocked a bolder loose. He turned around when he heard a rustle in the bushes. Nothing. He went back to work and heard the noise again. But still, he didn't see anything.
Crewman 5: "Must be my imagination."
He turned around to continue working one more time, and then...
"AHHHHUGH!"
Crewman 4: "What the?!"
Crewman 2: "What was that?!"
Crewman 5: "It sounded like Bob!"
The crew all went to check what happened. When they got near the spot where the man had been last seen, he was nowhere to be found. What they did find, however, was a pool of blood.
Chief Builder: "Bob! Bob!? Where are you?!"
As the crew looked into the forest, a set of glowing eyes suddenly appeared. No one had time to react, to defend themselves, or to call for help, before the sounds of terror, murder and death filled the sky. A terrifying creature had been disturbed and was now on a killing spree!... And West City was its first target.
