Jack-O-Bonnie is one of the nightmare animatronics and a major antihero in the Five Nights at Freddy's game series. Jack-O-Bonnie is a Halloween-themed variant of Nightmare Bonnie who first appeared in Five Nights at Freddy's 4 where Jack-O-Bonnie replaced him in a Halloween update. Visually Jack-O-Bonnie looks a lot like Nightmare Bonnie, but with added Halloween-themed colors to his appearance. His is brownish-orange in color. Like an actual Jack-O-Lantern Jack-O-Bonnie has his endoskeleton eyes replaced with eye sockets that glow orange and yellow, and the teeth glow a light yellow allowing the endoskeleton jaw to glow in low light.
