Phone guy attacked me in minecraft? Who is he?

A player named phone guy was in my game with me and my cousin. He was pitch black and he had a silver fish. It attacked us and it wouldn't take any damage from us. Is this a creepypasta? It won't let me open mincraft. Before he attacked me I tool a screen shot… Phone guy attacked me in minecraft Who is he

I'm pretty sure it was a person in another room ( if your in a hotel and apartment) Or hes across your driveway using your internet. I'm think phone guy is from Five Nights At Freddys and I think he made his skin like that because his skin he put in failed! So DON't WORRY!
