Balloon Boy

The Balloon Boy also known as either the Balloon Vendor or BB is an antagonist in Five Nights at Freddy's 2.

The Balloon Vendor starts in the Game Area and will eventually come to The Office via the Left Air Vent. He will stand on the left side of the room and greet the player with a "Hello," and will begin to giggle. Unlike the other animatronics, the Balloon Boy will not attack you himself. Instead he will disable your flashlight and both air vent lights for as long as he's in the office, making it harder for you to tell when the other animatronics are about to attack.
