Hello, you know the three discs 5,11 and 13, but... do you know the corrupt disc 12?, its center is red and it's corrupt, and it's very rare for many of us, let's talk about it in this blog:It is very similar to disc 11 in terms of the story, both contain the sound of running and escaping from a monster, but we will notice that disc 11 if we play it with disc 13 at the same time; They will fit together as one disk, but corrupt disc 12 is not, it is very mysterious and its story is different from disk 11, but let me tell you what happened in the disk according to my point of view:
THE STORY:
One rainy day, in a cave, a miner had built his house, and he was coming back and he was coughing, he was stepping on blocks of stone, and we hear the sound of lightning, and we hear the sound of an entity like enderman and this entity screams, and it makes those sounds again, the miner had not reached After to his house, he stops for a while to see the source of the sounds, and we hear lightning again, the miner runs quickly to his house escaping from the entity, opens the door of his house and enters, the entity shouts to start chasing the miner, and reaches his house, and he may have broken the door, and enters and kills the miner, and then a strange, glitchy music, perhaps condolence music for the miner's death, and the disc ends.WHAT IS ENTITY:
As for the insane entity in the corrupted Disc 12, according to the votes it turns out to be close to the Enderman; Or maybe enderman himself, we have to pay attention to something: the music disc with the audio object is added to the version together, for example disc 5 was added to version 1.19, knowing that warden was added in the same version, the post of the video I included for you dates back to 2019/ 8/22, which is the same day that version 1.15 was published, so the entities that were seen in this version and on the same date, which are similar to endermans, I only found in my search one entity, it's anomaly 099, so.. this is the source of the sound in Possibly, you can see information about it at: https://minecraftcreepypasta.fandom.com/wiki/Anomaly_099.
What is the evidence for the theory? In the previous link, you will find that among the capabilities of anomaly 099 are the following:
I-Glitchy sounds: We will notice strange sounds on the disc as well.
II-Player dying randomly: The miner died quicklyHerein lies some of the weaknesses of my theory.

This is all my theory and I hope you like it.
