Phantom BB or Phantom Balloon Boy is one of the antagonists in the game Five Nights at Freddy's 3, and is one of the six phantom animatronics in the game. He is a hallucination of a burnt and damaged Balloon Boy.
Phantom BB is essentially the same model as Balloon Boy from the second game, but he lacks eyes. He instead has small, glowing, white irises similar to Springtrap and is missing both his "Balloons!" sign and balloon. Phantom Balloon Boy also looks to be charred or burnt, possibly foreshadowing the torching of the attraction.
Phantom BB will sometimes appear and block a camera's view. If the player does not switch cameras, Phantom BB will appear in front of the player in The Office as soon as the Monitor is lowered.
Five Nights at Freddy's 3
Unlike in the second game, Balloon Boy is now hostile. Phantom BB lacks a movement pattern, but instead randomly blocks the Monitor view with his face, the frequency of this increasing as the week progresses. If the player does not change camera views before retracting the Monitor, Phantom Balloon Boy will appear in front of the player in The Office and proceed to lunge at them with a scream, disappearing and disabling the ventilation system. The time allotted to change cameras before his jumpscare decreases as the week progresses.
Five Nights at Freddy's: Ultimate Custom Night
Phantom Balloon Boy returns in Ultimate Custom Night. In this game, Phantom Balloon Boy behaves just like he did in FNaF 3, where he will randomly appear on the camera and if the channel of the camera or the camera isn't put down in time, he will jumpscare the player leading to a ventilation error.
