Nightmare BB was was of Nightmare's minions, he lived a short life of no more than a few days, and served more purpose dead than alive.
2020 Life and Death[]
Nightmare BB was summoned by Nightmare together with his other minions. He was left alone with Mangle and the prisoners in Freddy Fazbear's Pizza I while the rest of the Nightmares teleported away to deal with the escapees.
Death[]
During their absence, one day BB heard noise from the Kitchen and went to check it out. He found nothing and decided to come back later. When he did, he ran into Toy Chica. He tried to attack her but as he jumped at her, she threw her newly created Soul Sword at him. He was hit directly in the neck, and as the Sword pinned him to the wall, his head fell off and he died.
Post death[]
His body was later used by Plushtrap to test the AI for their army.
