Balloon Boy is the only animatronic in the game that will not kill the night guard, but rather he will make an annoyance of himself by disabling the Flashlight and Air Vent Lights all while a sound loop of him laughing will play until the player is killed or gets to 6 AM. If this occurs, the player is especially vulnerable to Foxy's attack, as he can no longer be stunned with the now disabled Flashlight. To prevent Balloon Boy from fully entering the office, the player must put the Freddy Mask.
