Nightmare Balloon Boy, after killing the player in Ultimate Custom Night.,

Nightmare Balloon Boy (also known as Nightmare BB for short) is an antagonist and a nightmarish counterpart of Balloon Boy, making his first appearance in the Halloween Update expansion (both Standard and Halloween Edition) for Five Nights at Freddy's 4, where he is featured in his minigame known as "Fun with Balloon Boy" and functions exactly the same as Plushtrap. It is confirmed that he has an impact on the lore; whether his role is important or not is yet to be determined.

Physical Appearance

Nightmare Balloon Boy's appearance is similar to the original BB, except with a more menacing design. This includes large, pointed teeth inside of his large mouth (similar to Nightmare Chica), dark-blue eyelids and teeth gums, long claw-like fingers, and more sinister-looking eyes with red irises (similar to Nightmare Chica's Cupcake) as well as narrow gray veins. In fact, his mouth goes all the way around his head. He has a red triangular nose and circular cheeks instead of orange ones. He also has a red and purple striped hat and shirt, instead of his usual red and blue stripes. The pinwheel from the top of his cap is also blue rather than orange with a yellow button up top. His two buttons are indigo instead of the original BB's black ones. His brown hair is slightly shorter than his original counterpart. His blue pants are lighter in color. If one looks carefully, one can see that Nightmare Balloon Boy seems to wear white socks. His shoes bear an exact resemblance to his original counterpart's, albeit they appear lighter in color. Interestingly, Nightmare Balloon Boy appears to be in a perfect and completely undamaged shape.

Like Phantom BB, Nightmare Balloon Boy lacks the balloon and "Balloons!" sign.


Unlike his original counterpart, as revealed in Ultimate Custom Night, Nightmare Balloon Boy talks in complete sentences. As with the other nightmares, he has no qualms about torturing his victims with his bony, metal hands. As evident by his quotes in the aforementioned game, he also has a tendency to mock his victims, whenever the opportunity presents itself. The chomping noise heard in one of his quotes suggests gluttony and bloodthirstiness.


Five Nights at Freddy's 4

Nightmare Balloon Boy only exists in the "Fun With Balloon Boy" minigame, which functions almost exactly like the minigame "Fun With Plushtrap". Nightmare Balloon Boy starts off on the chair and then moves to four sets of doors, hallway, the "X" on the floor, or jumpscares the player.

Nightmare Balloon Boy functions exactly as Plushtrap in the "Fun with Plushtrap" minigame, except for the fact that he laughs or says "Hi" or "Hello" in a deep, demonic voice as well as the fact that he moves at a slightly faster speed than Plushtrap (given the shorter timer), making him more of a challenge. His jumpscare is similar in fashion.

To win the minigame, the player must shine the flashlight when Nightmare BB is stopped on the "X", Nightmare BB will then permanently cease moving and the player will be granted a 2-hour bonus for the next night (1 hour is skipped when challenges are enabled). If the player fails the minigame and Nightmare BB is hiding in a room or still in his chair when the timer goes out, the player will receive a death screen with the words "TOO BAD". If the player fails the minigame and/or Nightmare BB gets too close before the timer runs out, they will be jumpscared by Nightmare BB and lose the chance to win the 2-hour bonus, also giving the player the "TOO BAD" result screen.

Ultimate Custom Night

When he is slumped over in your office, do not shine your light on him. When he is sitting up, however, you must use your flashlight to reset him.

Nightmare Balloon Boy returns in Ultimate Custom Night as one of the many selectable characters.

When the night starts, Nightmare BB is already slouched over inside the office. After lowering the monitor, there's a chance he'll be sitting up. When slouched, the player should not to shine the flashlight on him, as this will result in an immediate jumpscare. If he is sitting, however, they should shine the light to return him to his slouching position, otherwise he will attack when the player opens up the monitor.

The challenges in which Nightmare BB is present are as follows:

  • Pay Attention 1
  • Pay Attention 2
  • Nightmares Attack
  • Chaos 3

Five Nights at Freddy's VR: Help Wanted

Nightmare BB returns in Five Nights at Freddy's VR: Help Wanted as an antagonist. He appears in the second Dark Rooms level, which is a recreation of "Fun With Balloon Boy", where the player has 90 seconds to stop Nightmare BB on the X. Successfully stopping him unlocks PlushBaby's level, whereas failure results in a jumpscare from him, forcing the player to restart.

Five Nights at Freddy's 4

  • While the Halloween Edition was originally announced to not expand any lore of the series, Fun with Balloon Boy made its way into the Standard Edition. After causing some confusion among fans, Scott himself confirmed that Nightmare BB fits into the story and can be considered canon to the series.
    • This makes him the first canon animatronic in the entire series who was added to a game after its initial release.
      • This makes him the only animatronic to be announced as canon after its introduction as non-canon.
    • This also makes him the only part of the Halloween Edition that canonically expands upon the game's story and lore.
    • Additionally, this makes him the only canon antagonist in the fourth game who is based upon a character from the second game.
    • Furthermore, before Sister Location is confirmed, he is the only canon character who isn't a hallucination that does not appear in the Thank you! image.
  • Nightmare Balloon Boy, Nightmarionne, and Plushtrap are the only nightmare animatronic whose hands do not expose their inner endoskeleton.
    • However, Nightmare Balloon Boy is the only nightmare animatronic whose claws do not have any metal exposed.
  • This is the second version of Balloon Boy with a jumpscare, after Phantom BB.
    • It is, however, the first and only one of Balloon Boy's counterparts that is capable of giving the player a "Game Over", as Phantom BB's jumpscare merely caused a ventilation error.
  • Nightmare Balloon Boy is one of the three nightmare animatronics to appear in both the Standard and Halloween Editions. The other two being Nightmare Freddy and Nightmare Fredbear. This is because "Fun with Balloon Boy" can be selected and played via the Extra menu in both versions.
  • Nightmare Balloon Boy is one of the two nightmares in the game that are perfectly undamaged, the other being Nightmarionne.
  • In his jumpscare, Nightmare Balloon Boy appears to be beckoning with his fingers at the player, in a strangely human-like fashion.
    • As such, it is odd as to why the player's vision is shaking if Nightmare Balloon Boy doesn't really get to grip the player when he jumpscares, as all the other animatronics do.
      • This may be due to the player's character shaking due to fear.
  • Nightmare Balloon Boy is BB's only counterpart to have fingers.
  • Nightmare Balloon Boy, Plushtrap, and Nightmare Fredbear are the only nightmare animatronics in the game to close or even use their eyelids in the game.
    • Nightmare Balloon Boy and Plushtrap use them in their jumpscares, while Nightmare Fredbear uses them at the end of the demo where he is seen glaring.
    • Nightmare is seen glaring in Ultimate Custom Night but not in in Five Nights at Freddy's 4.
  • Nightmare Balloon Boy's head isn't connected to his jaw in any way, and simply floats in the air. It can be noticed in his jumpscare.
    • However, when he hides in the close right hallway and the close left hallway, his head is connected to his jaw by two cylinders.
  • Nightmare Balloon Boy is the only nightmare animatronic to have lighter colors.
  • Nightmare Balloon Boy is the only nightmare animatronic from the Halloween Edition with his own sounds. Nightmarionne and Nightmare Mangle use sounds from the second game.
    • However, Nightmare Balloon Boy's sounds are edited versions of his original counterpart's laugh from the second game.
  • This is the first time in the series where BB has been called Balloon Boy. Up until the Halloween update his name was never actually said to be Balloon Boy at all.
  • Nightmare Balloon Boy is one of the two nightmare animatronics that don't have any visible endoskeleton, the other being Nightmarionne.
  • Nightmare Balloon Boy, Nightmare Mangle, and Nightmarionne are the only animatronic counterparts that are not reskins of their original forms.
    • However, Nightmare Mangle's head is a reskin of Nightmare Foxy's.
  • Nightmare BB is the only nightmare animatronic to have human-like eyeballs.
  • This is BB's only counterpart to sport an "endoskeleton" teeth.
  • Nightmare Balloon Boy is one of the few antagonists from the series to laugh while being active. Others being Nightmare Fredbear, BB, Freddy and Golden Freddy from the first game, Funtime Freddy, Bon-Bon, Bonnet, and Minireena's second counterpart.


  • While sitting on the chair, Nightmare Balloon Boy's shirt appears to clip through his lower jaw.
  • In his jumpscare, Nightmare Balloon Boy's teeth visibly clip through one another.
    • From the first frame of his jumpscare, his thighs appear to clip through his torso.
    • His thumbs also clip through his fingers.
  • While Nightmare Balloon Boy is sitting on the "X", his nose can be seen through his right eye socket.


  • There is a glitch that sometimes occurs where the player doesn't win the minigame after Nightmare Balloon Boy sits on the "X".
  • The player can still access the minigame, even if they haven't beaten Night 8 yet.

Ultimate Custom Night

  • Nightmare Balloon Boy's voice in Ultimate Custom night appears to be based upon Andy Serkis' Portrayal of Gollum from the Lord of the Rings film series.
  • Nightmare Balloon Boy makes the Normal FNAF 4 Kill Scream when attacking the player instead of the Fun With Plushtrap mini game Kill Scream. Plushtrap also does this.
  • When the player starts the night, until they put up the monitor, Nightmare BB will not be provoked by them shining the flashlight on him. This also occurs if he was standing up and returned to his slouching position by the flashlight.
  • Matthew Curtis, Nightmare BB's voice actor, uploaded videos to his Youtube channel that involve him singing a song in his Nightmare BB voice:

Five Nights at Freddy's VR: Help Wanted

  • It is interesting to note that in in Five Nights at Freddy's 4 and Ultimate Custom Night, Nightmare BB did not have segmented fingers, unlike Five Nights at Freddy's VR: Help Wanted, where his hands resembles that of bones.
    • Nightmare BB's pupils have also changed, now black instead of white.
  • In the "Trick or Treat" level from the Spooky Mansion game mode for the Curse of Dreadbear cutscene, Nightmare Balloon Boy's jumpscare will trigger if the player fails to wear the corresponding mask as the original Balloon Boy opens the door.
