In the Night 5 mini-game in Five Nights at Freddy's 3 it is revealed that 'Spring Bonnie' was used by William Afton to escape the spirits of the 5 murdered children. Spring Bonnie made its first debut in 'Fredbear's Family Diner', the original location which lead to the creation of Freddy Fazbear's Pizza. Spring Bonnie was an animatronic functioning with 'spring-locks', created alongside Fredbear, and one of the first animatronics created and used at a location in the FNaF storyline. Springtrap is a withered, decayed Spring Bonnie suit, in which William Afton died, his soul becoming trapped. The hands are mostly complete but the thumb and the first finger of the right hand are missing, showing the endoskeleton fingers, the left hand is mostly complete except for the second part of the ring finger that is missing. The eyes are grey and look like human eyes the size of animatronic eyes, in front of the eyes are light grey circles.

One red, black wire and two green wires are sticking out from the bottom of the large hole. The face has multiple holes and a larger hole on the right side of the top of the head exposes the Purple Guy's rotten corpse's head inside. The left side is the most decayed (or missing), showing part of the endoskeleton with a red wire poking out of the suit's ear, the right one is less decayed (missing) but the ear still shows some decay. The teeth are mostly exposed, having a yellowish tint. The suit has several holes ranging from small to large in size. The suit is an olive green with a forest green belly patch as well as the inside of the ears.

William Afton, the main antagonist and serial murderer of the Five Nights at Freddy's story, is trapped inside Springtrap, having his body punctured by animatronic parts following a springlock failure in the Safe Room. Springtrap is the main antagonist and only physical animatronic featured in Five Nights at Freddy's 3.
