The creature in front of me is the most horrifying being I have ever seen, in the books, movies I have seen many terrifying things but not as terrifying as this.
It had the near-circular center of hundred meters, and from there, thousands of tentacles came out. Its center (Head) is abominations, there is a large vertical mouth, which covered nearly all the center and both sides of the mouth had hundreds of eyes.
This is just the starting; if it had been this, I would not have shaken to the core.
The most horrifying part is its tentacles, they are spiky, and each tentacle had at least ten eyes and mouths, from which slobber could be seen coming out endlessly.
When one looks at the complete form of the creature, they will find their spine-tingling in the cold sweat, and they are taking steps back unconsciously to get away from this Abomination.
