The server terror

I was once playing minecraft on a sever. There was a desert temple. For a shot seccond I thought I saw what looked like Green steve. I though " It can't be its just a player". Over the next few days Other players said they stuff like villagers goneing missing and something kill then from the back and after words most of there food taken. Some said they saw a player that looked like the one I had seen. Told some people about it. The admens tryd to block him but could not find him in the list of players it was clear that this mystery player was no player but some kind of mob. I started forming an army to fight this mob. I got 25 players and we march on the temple. We spotted the green steve like beast and we attack it. But Meny hit other players by axadint and soon a battle broke out bettewn ourselfs and the green mob snuk away.
