Something strange happened on the 1.13 beta...

As you guys may know, the update aquatic is coming soon, with a beta currently out. I decided to mess around a bit. I decided to explore an underwater ravine. Then around fifty drowned mobs spawned right by my boat. Luckily I had my trusty enchanted trident, but fifty drowned? That was odd. Nevermind, I just continued down to the one spot where my friend said he died. Weirdly, squid, turtle, drowned, and fish just sat there just like they weren't alive. My game started to lag so I decided to kill them. No luck. There was an iron trapdoor next to gold ore. I didn't care about the gold, I cared about whatever was down there. Bad choice as you can guess. It seemed like a storage room. It was filled with shulker boxes. Some filled with wood, others stone, some filled with fish buckets. A group of six drowned interupted my rummaging. They had seemed to have red markings on their eyes. The drowned just floated to the bottom and laid on their backs like all the other mobs in the ravine. A sign popped up. "No escape from IT" the sign said. I opened a door. A giant statue of A truly monstrous beast sat in the middle. Four legs. Teeth formed a split beak. Tail fluke. It was no animal. Before I could leave, a child screaming blasted my earphones. This thing was clearly dangerous. I opened a door not knowing what I got myself into. There it was. Standing there with blood all over its mouth. The creature that looked like the statue. A player with a little kid skin lay face down on the floor. My chat became flooded with the number 666. It can enter chat and kill, what's not to fear. I threw my trident at the beast, but it swallowed. Then the trident shot out its throat. Still alive. It walked up, got up on its hind legs and starred. It was twice my height on all fours and now it is six times my height. It grabbed me and opened its mouth. Its mouth was nothing but teeth. Not even a toungue. It threw me in. I was losing health as if it were lava. The death message said: [Insert player name here] has taken the wrong path and got eaten by the devil.
