Most pasta agree wholeheartedly that the most terrifying/disturbing thing they have seen in all their time as a creepypasta is the sight of EJ unhinging his jaw to let out all four of his tongues.
(So, I don't usually roll with the headcannon of EJ having four tongues (is it canon? Idk- omfg I just realized I've been spelling headcannon wrong the entire time and here I am shaking my head at those spelling it correctly omfg my life is over) but I was on tumblr and saw a post kinda similar to this which made me think of this so here we are :3)
