Windup Bonnie is a light-blue windup rabbit toy with some white on both his stomach and muzzle. He seems to have long sharp black whiskers and seems to be sporting small sharp teeth with two buck teeth. His gums are exposed, similar to Dream Animatronics. Just like original Toy Bonnie from Five Nights at Freddy's 2, he has bright red cheeks and he wears a large red bowtie and has a red guitar. Unlike Dream Animatronics, he has black shiny sphere eyes instead of having buttons.
- Windup Bonnie's appearance is based on Toy Bonnie's appearance from Five Nights at Freddy's 2.
