— Nightmare BB's loading screen.

Nightmare BB, fully known as Nightmare Balloon Boy, is an unlockable character added to the Update 1.2 for FNaF World. He is a nightmarish version of the original BB. He can be unlocked by beating Foxy Fighters with an A rank.


Nightmare BB's appearance seems identical to his regular counterpart from the core series but smaller and "cuter" with shorter legs and larger eyes with slightly small pupils.


Mega BiteDeals an incredible amount of damage to enemies.
BubblebreathProtects party from toxic effect.
Balloons2Summons a large amount of balloons.


Nightmare BB is an extremely powerful character to use and one of the two characters that is needed for the Geist Lair. Nightmare BB has Mega Bite that can do huge damage to an enemy and others nearby.

In the Geist Lair, Nightmare BB can use Bubble Breath to prevent all the characters health from draining quickly. This can last between 1 to 2 minutes.

Nightmare BB's best attack however, is Balloons 2, unlike Balloons that summons 3 Balloons, Balloons 2 summons 30 Balloons that can do huge damage to the nearest target, if killing them it moves on to the next. In addition, each Balloon has a double chance for bigger damage which is usually around 200 damage per balloon.

  • Nightmare BB's loading screen likely refers to the fact that, outside of some slight eye and proportion changes, his appearance is more or less unchanged from Five Nights at Freddy's 4.
    • It could be assumed that Nightmare BB's appearance is what Balloon Boy could have looked like during the events of Five Nights at Freddy's 4, rather than his incarnation in Five Nights at Freddy's 2.
      • However, Nightmare BB lacks some traits of the original BB, such as the purple stripes instead of the blue ones and possesses no balloons.
  • His idle animation is similar to Phantom BB's.
  • Nightmare BB is the only character that has Balloons 2.


  • When Nightmare BB attacks, one of his buttons clips through his jaw and his left thumb clips through his head.
  • In the Update 2 teaser, Nightmare BB's rosy cheeks can be seen clipping through his skin and appearing inside of his eye sockets.
