you created a minecraft world for fun and you forgot to change it to single player mode, now your world is multiplayer, but still survival, you were chopping some tree and making your own base but as soon you were trying to get some more woods for your base but as soon you were gonna chop the tree, the tree teleported far away from you, you were chasing the tree for hours and you got so tired and you were going to chop the other tree but it teleported?! You heard some laughing and giggling noises from the sky, when you looked at the sky, you saw a wither skeleton flying, and it's a hacker, but still a mob maybe? And he was teasing you or making fun of you and he was having that cheeky smile Wither skeleton: Awwww! Someone is mad~
