Spring Bonnie is a bulky, animatronic golden rabbit with a large head, not too difficult from Nightmare Fredbear's with square teeth in his wide mouth. In the cover, his eyes are small and blue, with apparent flesh surrounding them and a black oil looking liquid oozes from his left eye, while his eyes are blank in the unused illusion, with slightly thinner limbs attached to them. The book describes him as looking organic with an unhinged jaw and two rows of sharp fangs. Spring Bonnie first appeared during one of Oswald's visits to Freddy Fazbear Pizzeria in the past, through the ball pit at Jeff pizza. Nobody seem to notice the golden rabbit except for Oswald. During another visit, Oswald spots Spring Bonnie standing lifelessly in a corner of a room, staring. On Oswald last visit to Freddy's, something is amiss, as customers screen and escape the pizzeria. Spring Bonnie lures Oswald to the back room of Freddy's, where he sees Spring Bonnie six other children victims, who were murdered and had party hats put on their heads. Spring Bonnie pursues Oswald toward the present day, where oswald father is waiting. Suddenly, Spring Bonnie drags Oswald dad down the pit and emerges from it, taking Oswald into his dad car and quickly driving off. For a couple of days, Spring Bonnie seems to just impersonate Oswald father, even Oswald mother finds nothing wrong with him. It watches television, sleeps in bed and drives like a normal person. Only Oswald and possibly his cat can see Spring Bonnie for what he truly is. What caused his end is that Oswald manage to get him to be strangled in the ball pit net and dies.
