Before being swapped out, Spring Bonnie's head looked noticeably different in comparison to the "Remember Jeremy" teaser.In a later teaser Spring Bonnie was swapped out in favor of Nightmarionne. In the first few teasers for VR, Spring Bonnie was shown.However, it was eventually found that the footage had to have been of Glitchtrap instead, as the footage came from a version of the game that was made after Spring Bonnie was removed. Footage of Glitchtrap in an older version of the game was believed to have been Spring Bonnie due to the lack of a visible model.A majority of Spring Bonnie's design aspects, such as eye color and his bowtie, originate from his appearance in FNaF World.Spring Bonnie's origin is very strange, as he was first mentioned in FNaF 3, appeared as a background character in FNaF 4, and got his only 3D appearance in FNaF World (if VR's teasers are not counted).Spring Bonnie's unused model showcased in the Ultimate Guide Book.

Spring Bonnie's behavior in the game is heavily implied to be the exact same as Glitchtrap's, as many early files and video footage imply that Glitchtrap took his place once he was scrapped from the game. He would then go on to possess the suit and become Springtrap. His carelessness caused the springlocks to snap, killing him. Once he thought he'd won he began to laugh. He would then put on the suit in an attempt to scare off the souls of his victims. William Afton later would find the suit in the saferoom after disassembling the Classic Animatronics to find that his victims souls were inside. After this is was stored in the safe room. When the restaurant closed down, the suit was used by William Afton to lure and kill five children. They, alongside Fredbear, preformed on-stage at the diner. Spring Bonnie was a springlock suit used at Fredbear's Family Diner. When the Ultimate Guide Book was revealed, it showcased an image showing the unused model of Spring Bonnie, showing it was very similar to Springtrap's model, but with a thicker head and smaller jaw, as well as using Plushtrap's endoskeleton rather than a simple edit of Springtrap's. Due to FNaF World being his only appearance outside of an 8-bit sprite and VR's teasers, not much else can be said about what the character looks like.

In his early appearance in VR, his eyes were seen glowing purple. He's got yellow fur and his FNaF World appearance shows that his eyes are colored green and that he wears a large purple bowtie. Spring Bonnie is an animatronic rabbit and also an unwithered version of Springtrap.
