Entity 3rr0r

First encounter

One day, i was feeling bored and decided to play Minecraft. I was playing in the new 1.13 snapshot. Then i created a new creative world with a seed called 3rr0r. I thought it was funny thinking nothing bad will happen. But i was wrong. When i tried to place a block, it randomly turned into a weird dirt block looking block but with numbers on it. And the numbers were 3rr0r. Just like the seed i put in. I thought it was a bug in the new 1.13 snapshot so i emailed the developers. They said that they didn't do anything wrong. Now i thought that was weird. When i went back in the world, i saw a sign that i didn't place and it said "3rr0r. 1s. C0m1ng." And i thought that was creepy but i still decided to play. And that was one of the most horrible mistakes i ever made in Minecraft. When i opened the inventory, all the blocks were black and white, and they were all named 3rr0r. When i closed the inventory, i saw a mob 25 blocks away from me. I took a closer look. The mob was completely black, execpt for it's hands, eyes, and mouth. The eyes were blood red, the hands were green, and the mouth was blue. I freaked out, exiting Minecraft. I uninstalled Minecraft and swore never to play it again.
