Why does the Owl disregard your exposure meter? Since your exposure doesn't increase when the lights are off, it's a safe assumption that it only increases when the monsters can see you. Owls can see in the dark, meaning turning the lights off would do nothing, so the game just cuts to the chase and has the Owl instantly kill you instead of making you deal with Controllable Helplessness.
In One Night at Flumpty's, there is a map of Utah on the wall on the player's "office". Why is this random map here you may ask? Simple: The Five Nights at Freddy's novels are set in Utah, and it is implied that also goes for the games too, so of course a fangame of the series would not only take place in the same universe, but also take place in the same setting too.
In 3, why does Flumpty say you never made it to 6 AM in any of his games? Simple. You made it to H/SP AM, not 6 AM.note And if it is Breaking the Fourth Wall and the player hasn't played/beaten the first two games, the point still standsThe developer commentary and the ending of the third game both confirm this. In the normal mode, you make it to SALAMI, not 6 AM, and get the bad ending. When you clear Hard Boiled Mode, you actually do make it to 6 AM and get the good ending. Look at the clock in the ending cutscenes in 3; the bad ending's clock doesn't have "6" on its face so you'll never get to 6 AM, but the good ending's clock has "6" so you actually got to that time.
The ending after Flumpty Night in 3 could be considered an Ass Pull, if you haven't read the newspaper in 2's Hard-Boiled Mode ending. Flumpty caused the apocalypse with that meteor, meaning that during your time playing his games, everything already went to hell. It's only 3's Hard-Boiled Mode ending where Flumpty restores everything.
Grunkfuss' gimmick of not wanting his picture in 3 taken might be seen as a unique function, but it makes sense if you check CAM 6. It's a museum of clown art, and is Grunkfuss' starting location. Museums are known for putting 'No Flash Photography' warnings in various exhibits (to prevent painting damage).
This could also explain why Grunkfuss looks like he is shielding himself in the credits. He in general HATES getting his picture taken.
With these in mind, his gimmick in general tends to revolve heavily around cameras, and attacking in relation to their presence around him. In ONaF 1 he slowly enters the room more and more as you use the cameras, presumably because he just hates the system and the noises it makes. And in 2, he has a patience meter that you can only reliably keep track of without memorizing it by turning on the camera in his room, with his patience likely relating to how long he's willing to sit in there with the camera running.
The fact that Flumpty gets a second night all to himself in 3 doesn't make "One Night At Flumpty's" an Artifact Title. Typically, the titular five nights take place over a week, one night after the other, but Flumpty's Night isn't the next night after, it's the first night you just finished, but Flumpty rewound it. You technically are still doing one night at Flumpty's.
Why does Flumpty kill the other characters? Because they're his "friends", as are you. They're all playing his game, albeit in a different role from what you're doing. When you lose his game, you die. When they lose the final game against you, they die.
Eyesaur doesn't attack the player in 1, but when Grunkfuss appears, an eye will close depending on Grunkfuss' current state. How does it know when you flip your tablet, and know how far Grunkfuss is in your office?
Eyesaur consists of Flumpty's past victims. Basing on the number of eyes, in 1, it consists of 15 people (30 eyes / 2 eyes per person = 15 people). In 2, there are 10 people (20 / 2 = 10). In One Week, 11 heads can be spotted. In 3, there are 10 heads in its texture for when it is at the door. But how many people became victims to Flumpty's game before he had the idea to create Eyesaur? Are there more victims in Eyesaur than the amount of heads shown in their respective games?
Well of course not. They reached HAM and SPAM, not 6 AM
According to 3's Developer Commentary (kinda), if you include all the main nights, the Hard-Boiled nights, and Flumpty Night, the player spent one whole week in Flumpty's world.
The title screen for 3 features Flumpty covered in blood. This isn't just to be creepy, it's Foreshadowing. That's his buddies' blood he's coated in.
In the cast roll for 3, Redman, Grunkfuss, Beavowl, and Eyesaur look tense rather than the goofy and carefree attitudes of Birthday Boy Blam, Golden Flumpty and the egg himself, especially compared to the credits in previous games. Combined with how their personalities work, its likely that these aren't just incidental sketches; they're the last time these characters were seen alive moments before Flumpty slaughtered them for their failures.
