The terrible call of Cthulhu

We tried to open the door, but we failed, so some of us started climbing over it. Suddenly, we found it opening slowly in a strange circular motion! Revealing a darkness so black that we felt that the sky had also darkened due to the intensity of the blackness emanating from the door opening, and the smell emanating from that foul place was unbearably disgusting and repulsive. Hawkins, our companion, indicated that he heard something slipping from under us. So we remained silent, listening carefully... Suddenly, we saw a huge, soft, green, gelatinous entity emerging from that hole. I cannot describe the ugliness of what we saw, as if it was a screaming, crazy inferno, defying all known laws of the universe, but I can say that two men from my crew died from extreme panic. At the same moment he appeared, three others fell lifeless bodies when their bodies came into contact with the touches of this suspicious creature!
