"And with a shriek.... it devoured its prey"
The Shrieker - a terrifying subterranean creature that is but one of the horrors of this wasteland world.
Called thus, for the blood-chilling shriek it lets out when it's about to feed, this creature is super stealthy and super fast as it slithers in the sand using claws that enable it to dig. But its speed pales in comparison to its brutality. It will devour anything that it senses. As it's a creature that lives underground, it has no eyes... but don't let that fool you - it can sense vibration miles away. It is also really hard to kill, due to the bony plating on its back that protects it (not to mention, its gargantuan size).
Shriekers also have a form of camouflage, so they can change color to match their environment - The sand color it dons, is to camouflage itself in the sands of the desert. They can also turn red and black on a whim.
Fortunately, it is only found in one semi-shaded area of the desert, as its too hot elsewhere.
This place is known as the lair of the Shrieker. And you don't want to get caught there...
