Endo-Springbonnie

Endo-Springbonnie is one of the main characters from the FredBear's Scratch Series, serving as Springbonnie's endoskeleton.

Background
Endo-Springbonnie is, as his name suggests, the endoskeleton of Springbonnie, a golden rabbit animatronic from FredBear's Family Diner. He is the insides that have been taken out to make room for a human to fit inside Springbonnie, but he remains active still, despite being out the suit.

Role In Story
Endo-Springbonnie was made to obviously fill in Springbonnie when a worker couldn't wear the suit, but after the place shut down, Endo-Springbonnie was moved to several different locations as a result of this, but he always would find a person who was "Trespassing" as his programming made him always assume he is in FredBear's diner, thus at night he attacks people who trespass.

Office Duty
Endo-Springbonnie appears, but simply is called Spring-Endo. He acts as a wind up music box, simply needing to be wound up to not attack the player.

FredBear's Old Location
Endo-Sprinhbonnie crawls in the vent, and the player must shut the lights off to avoid them.

FredBear's Old Memories
Endo-Springbonnie appears in the night "The Endos Of The Past" where the player must simply play audio when he awakens, before he can attack. The Audio causes him to deactivate, as he thinks a show is playing, thus it is ok for the player to be seen.

FredBear's Ultimate Custom Night
This game has Endo-Springbonnie simply arrive at a door, and needs to be blocked off by it. The reason the mechanic is so simple, is likely due to the fact there is so many animatronics.
