After killing Coolplayer303 in your singleplayer game in Minecraft so many times, you get jumpscared by a meaty image of someone's skin if taken off for a second before it disappears and this shows in Minecraft chat after he dies and stops respawning and it made a scary noise.

"もう全部うんざりだ、君が嫌いだ、この世界が嫌いだ、外に出させてくれ、外に出させてくれ、君を見つけて、外に出てやる。" (Translation: I'm sick of it all, I hate you, I hate the world, let me out, let me out, I'll find you and I'll get out.)
