Springtrap is a rabbit-shaped animatronic that has been neglected for a long time and is severely worn out. He has a yellowish-brown appearance overall, with numerous holes and tears in the old, shredded suit that reveal the internal mechanical structure. One ear is badly torn and drooping, while the other stands relatively upright. His eyes have prominent white pupils, and his face has human-like expressions, giving him an uncanny feeling. His overall form is a mixture of an old rabbit animatronic and broken machinery, leaving a very aged and eerie impression due to the exposed wiring and metal parts. Thirty years ago, while being chased by the souls of children, William Afton happened to see the Spring Bonnie suit he used to wear at Fredbear's Family Diner in the safe room. He put it on, but unfortunately, it was a humid day... Eventually, the springlocks inside Spring Bonnie malfunctioned, crushing William's entire body and killing him. However, thirty years later, William, who had been trapped in the safe room, regained consciousness. Springtrap is sensitive to audio lures and is easily deceived by them.
