The Bite of '87 was an incident that occurred in 1987 at the second Freddy Fazbear's Pizza location. It was briefly mentioned by Phone Guy in the first game.
The details of this attack and the identity of the animatronic
responsible are unknown, but it allegedly caused the victim to lose the
frontal lobe of their brain. The victim survived the attack.
The incident contributed to a loss in the company's reputation, which was one of the numerous incidents that resulted in a major drop in business going forward.
As a result of the incident, the
animatronics were no longer allowed to wander around the building during the day; the management decided to limit their free-roaming mode to nighttime, so as to "prevent their servos from locking up", as stated by Phone Guy.
