Being a person who read alot of creepypastas, when I found out that he created a mod that would flash Terror Faces across the screen, and the addon that makes it so that it follows you, I downloaded that mod and scared the living crap out of me. I'm talking about Renderman. It's the Blockland version of Herobrine.
Video of Filipe1020 (He's a good friend of mine) using the mod:

Have fun having nightmares that involve the Ascii Terror Face.
