Springtrap

Springtrap was originally a Spring Bonnie suit that doubled as both an animatronic and a costume suit. It was used along with another similar suit called Fredbear in the Fredbear's Family Diner. After Fredbear's Family Diner is closed down due to a certain accident, the restaurant chain renamed itself to Freddy Fazbear's Pizza, and stopped using Fredbear and Spring Bonnie due to them being very dangerous to use because of its faulty springlocks. The suits are kept in the safe room in the restaurant that no one is allowed to access.
