Freddy Fazbear's Pizza

The kid - as in, the person you're playing as - is the Bite victim. The culprit is, naturally...the one animatronic not seen before the game, Fredbear.

I am thusly confused as to how Plushtrap exists. .

That brother is a complete jerk, and his parents aren't much of a help either, forcing the poor kid to have his birthday party at the very place that causes him to have nightmares after only one visit before. >_>
As tragic as the tale is, I really want to know why the other kids hated the boy so much...

Overall, it is just sickeningly sad.

I believe that the only thing Our Child Protagonist dislikes about Freddy's is the animatronics - he actually likes the characters and maybe other stuff about it, but definitely the animatronics; he has a Freddy plush on his bed and, if you close the closet door long enough on Nightmare Foxy he turns into a plushie as an Easter Egg.

Yeah, he saw the plushes as his only friends. But he still hated Freddy's because the animatronics are the main attraction, otherwise i dont know why he would be so distressed that his birthday party would be there . I imagine his family went to Freddy's often, maybe one of them worked there, and would bring back prizes. That may also explain why one of the mini games shows Mangle parts in the house. :shrugs:

The Kidtagonist is, to be blunt, a social outcast. Kids his age don't like him because he's a wimp. His older brother delights in torturing him. His parents don't give a flying fig. They're even hosting his birthday party at his least favorite place: Freddy Fazbear's Pizzaria (or perhaps Fredbear Family Diner? I'm not too sure about that, though in my mind Fazbear's would make a mote more sense) due to his automatonophobia re: the animatronics. Oddly enough, though, he loves the actual characters; the plushie versions of them are who he considers his only friends. (By the by, we can confirm that the Kidtagonist is a he; we actually see him in the between-night minigames! And there's talking!)

His automatonophobia is perhaps the source of the nightmare animatronics; they aren't actually there, he's just being a kid and afraid of the monsters in the dark. ...Don't ask me why they still attack from 12 to 6. I'm not a psychological doctor. Even if I try to be.

So the kid's able to stay collected for five nights, and it's his birthday party! Sucks that it's at Fred's, though. During it, his brother and his friends manage to trap him in the Parts and Services Room (?), and there is the original Fredbear Animatronic. The brother lifts the Kidtagonist up to Fredbear's open mouth...

...and snap. It closes. The Bite of '87 has just happened. The teens look on at horror at what just happened.

(Incidentally, this is why I think it would make sense that it occurs at Freddy's diner rather than Fazbear's; why would Fredbear be in the Parts and Service room otherwise? And since Freddy's was open during 1987, as per FNaF2... Of course I could just be a derp and not remembering stuff correctly.)

Oh, and by the way. Fredbear? Wasn't just created for convenience. See...he's colored yellow. He has a purple hat and bowtie. ...And he's a bear. That might sound familiar, and if it does, congratulations! You have just figured out that Fredbear is Golden Freddy, or have just done so after reading the first part of this sentence. (This can make even more sense when you realize that G. Freddy's mouth was always open.) I've heard that some fans were upset that the Bite wasn't purposefully inflicted by the animatronic, but not everything has to be the result of the animatronic's murderous impulses. (...Also with the Kidtagonist being the victim, it would make sense. The non-imagined versions of the animatronics defended kids.)

In case you're wondering about more technical details (because goddamn if there's one thing I'm a nerd about it's the technical details. No, really.):

• As per the first game, Nightmare Bonnie will always come from the Left Hall, and N. Chica will always come from the Right Hall.
  
• You can only ward them off by shining your flashlight at them when they're far away. Doing so when they're close results in a jumpscare.
  
• The cupcake can jumpscare you if you ignore Chica for too long. Bonnie accepts no substitutes and always will kill you.
  
• If an animatronic gets close, you can hold the door shut. How this works is a mystery, but they're not there, so uh.
  
• Also as per the first game, you check on Foxy in a separate location from the rest of the guys. If you shine the light on him and he's there, you have to slam the closet door as fast as possible. Neglecting to do so will kill you, obviously.
  
• Freddy, finally, does something different from the first game. Throughout the night, Mini-Freddies will congregate on the bed. A short while after three of them gather, they will activate Polymerization and fuse into Nightmare Freddy. See him and it's game over.
  
• Nightmare Fredbear performs the role of all of them Night Five.
  
• A mystery animatronic known as Nightmare randomly appears. Sometimes he kills you in a Golden Freddy-esque fashion.
  
• Plushtrap appears in a between-night minigame called Fun with Plushtrap!, i.e. Satanic Red Light Green Light. You have to lure him onto an X. Doing so gets you two hours into the night off the bat!  Failing to do so (you have a 60-second timer, so not doing that or... I guess having him go too far?) gets you nothing. But maybe a jumpscare.  ...About halfway into writing this section the FNaF wiki started constantly redirecting to a porn site. I was going to post a picture of him, because goddamn he's creepy, and if I'm having nightmares then so are all of you, but the best picture I got for him...is from the FNaF wiki. Yeah, no. I'm running a scan right now. (There are, of course, other pictures, but that's too creepy. ...Also don't look up fanart for Plushtrap. Totally misses the creepy vibe you get from him. ...I'd say especially the humanized artwork, but then again, when didn't that happen? Shit, look at TS's avatar. I am legitimately not scared of that shit.)
  

I can't think of anything else to add on, except for the fact that, sadly, everyone's favorite Phone Guy failed to make an appearance. Also that it's totally my headcanon that FNaF3's guard is Mike, but that's neither here nor there.

Is it possible to not look at the bed without consequence?
Also is nightmare freddy and nightmare fredbear the same character?

Nope. If you don't look at the bed, the Mini-Freddies will accumulate, and Freddy spawns. I presume he'll attack after a while.

And Nightmare Freddy and Nightmare Fredbear are not the same character. Well, from a certain point of view, they are, because on Night 5 N. Fredbear takes up N. Freddy's duties, but he also takes up everyone else's duties, so that's a moot point.

Point is, they aren't the same guy, much as Freddy and Fredbear/Golden Freddy aren't the same character.

I mean is there any differences in appearance?

Well, N. Fredbear is gold/yellow, with a purple hat and bowtie (obviously). He also lacks the Mini-Freddies, and is a bit portlier.
