Nightmare Balloon Boy

Nightmare Balloon Boy is an animatronic from the fourth Five Nights at Freddy's game. He is a nightmarish version of Balloon Boy from the second game with red irises and white pupils, several rows of sharp teeth, and long claw-like fingers on each hand.

Gameplay Mechanic
Nightmare Balloon Boy will start the night slumped over in the player's office. The player must be careful not to shine the flashlight on him when he's sitting slouched over, or else he will attack. When the player lowers the viewing monitor, Nightmare Balloon Boy will sometimes be standing an attacking position. The player must then shine the flashlight on him to avoid getting jumpscared.

Death Screens
Nightmare Balloon Boy will jumpscare the player with the same sound effect as the other Nightmare animatronics. He has several lines of dialogue that may play over the "Game Over" screen:
 * "Come closer. Help me count her teeth."
 * "Heheheheheh. You're not so big. Just a bite-sized morsel."
 * "You knew I'd get you eventually."
 * "There just isn't enough room in here for both of us."
 * "Flash that light all you want. It can't save you now!"
