Balloon Boy, often abbreviated to BB, is a human child-like animatronic, a major antagonist, and one of the toy animatronics of the Five Nights at Freddy's series, first appearing in Five Nights at Freddy's 2. He serves as the balloon vendor of the newly refurbished Freddy Fazbear's Pizza of 1987. After the pizzeria was only open for a few short weeks, it was then closed down, and Balloon Boy, along with the rest of the toy animatronics, was scrapped due to possible malfunctions.
