Phone Guy is basically your guide on the game, who was voiced by the developer, Marisu Paua.
Phone Guy's appearance is never actually revealed. I don't maybe, maybe Marisu will shed more light on it in the second game.
Night 1 Edit
"H-hey, HEY! Congratulations on the new night watch job! I actually worked in the place before you. Crazy, huh? I'm finishing my last few days, in fact. Anyway, I recorded this message to help you get settled in on your first night. I know it can get quite overwhelming there, but you are going to be fine! Things do tend to get a little weird at the night time, but there's nothing to worry about. The animatronics do get a bit mischief at night, so be aware that the girls do tend to explore the place. They are put in some sort of night mode, so they're limbered up for the shows in the daytime, or something like that. But anyway, the only real risk would be, if any, is the fact that the girls here, uh... if they see you, will play a bit... rough. Now that might sound good for some people, but with the heavy aspects they have, you can imagine the discomfort... and death. Uh... yeah... they don't tell you these things when you sign up. But h-hey, first day should be a breeze, I'll chat with you tomorrow. And... remember, check those cameras, and remember to close the doors ONLY if absolutely necessary. Got to conserve power. Alright, good night."
