Greg Mac Lochlainn is a one Phone Callers from Five Nights at Treasure Island: Found. He talks on Night 1, and is very friendly towards the player. It is very likely that he is in charge, or a higher-up, of the research team, as he mentions legal issues in his call. He also mentions a photo-negative suit, and tells the player that the suit can't see, but has good hearing. Shortly, after, he says, "Now, I'm sure you've heard the rumors floating around the workplace, and legally, I can neither confirm or deny any suspicious activity due to a... supernatural being", further suggesting that he is the leader of the research team. He then goes on to explain the main game mechanics of Five Nights at Treasure Island and hints towards Henry before ending his call.
Greg can never actually be seen in-game. Though, according to his promo, he has short brown hair, orange eyes, peach skin, and a small black goatee.
== Phonecall script == Hey, bud! This is Greg. Thanks for helping us out with this, again. Normally, we'd have one of our staff be the night watchman, but we're, uh, still stuck in Alabama, getting our equipment together to ship back... so, I guess an intern will have to do! And, uh, don't worry, I-I know you'll be fine. The last intern just... well, uh... A-anyway, we've already set up cameras for you to keep an eye on the place, and more importantly, we need you to, uh... keep a close eye on a suit for us. You'll see him lying down, he's Photo-Negative. You really can't miss him! Now, I'm sure you've heard the rumors floating around the workplace, and legally, I can neither confirm or deny any suspicious activity due to a... supernatural being. But, uh... let's say, hypothetically, if something were to get into your office, it's very important that you make noise somewhere else in the building.
We found that shutting off one of the cameras seems to work. Because, well, it can't really see... but it has pretty good hearing... and you'll need to react quickly... Anyways, I've gotta get back to packing up the gear so we can head back. 'Till then, check those cams, and we'll, uh, see you later!
