Wait, Cthulhu is a brony? We're talking aout the destruction god Cthulhu right, not some weirdly named dude, right? ...wow. So Cthulhu is taken to Equestria apparently and... Oh, just read the story. I have better things than to type up a long description of all this craziness. Just... read it.
I don't own MLP. I don't own the pic. The pic is filler until I find or make a better one. Think you got one that'll fit? Please tell me in the comments!
