Freddy Fazbear's Pizza II (1987)[]
Balloon boy was given life by the Puppet together with the toy animatronics. He was on Puppet's side during the conflict with Golden Freddy. He often played a supporting role in attacking the Night guard there, and was present during the final showdown of the conflict when Golden Freddy killed him and the rest of the toy. The place closed down due to a murder.
Freddy Fazbear's Pizza II (1993-2016)[]
6 years passed and a new Pizzeria opened, where they moved all the animatronics. Balloon boy was still among the dead toys, until Golden Freddy made peace with the living animatronics, and helped revived everyone including BB. throughout the years some animatronics felt annoyed with BB's laugh and search for attention, so they built a friend for him- JJ. They just ended up being 2X annoying. They lived in peace for almost 30 years.
Fazbear's Fright (2016)[]
The peace was broken when Springtrap was released and attacked everyone. BB got damaged as well. Everyone got moved to the new horror attraction, where Springtrap turned BB into one of his mindless phantoms. He was under Springtrap's control until one of the animatronics who weren't phantoms, helped him regain his memories and so he returned to their side (it's unknown which Animatronic saved him). Later Golden Freddy went against Springtrap and the building was set on fire. Balloon boy teleported with the others to the third Pizzeria only to find out it's on fire. He was then moved by the owners to the first Pizzeria instead, where Golden Freddy and Springtrap who stopped being evil, turned all the phantoms back into their original selves, so BB was back to normal.

Everything was fine until Nightmare was released by the traitor. BB was present during his attack, and was with the group that failed to escape and got captured by Nightmare. His eye got damaged in the process. After 3 weeks of imprisonment BB, JJ, Chica and Freddy have been used as a bait to be framed for the killing of cops who came to check out the place. His body got immobilized as he was posed next to a cop's body, waiting for the backup to find them.
