Nightmare Spring Bonnie

Nightmare Spring Bonnie is a Nightmare animatronic and bears a resemblance to Nightmare Fredbear or Nightmare Freddy as he is known throughout the community. Nightmare Spring Bonnie only appears on Night 8, the "Challenge" Night, and upon completion of the Night, the player will unlock a 4th star and plush versions of Chica, Bonnie, Spring Bonnie, and Fredbear for the player's Bedroom. Many of the plushes will be scattered around the room in different places such as on the floor and along the top of the dressers.

Appearance
Nightmare Spring Bonnie is based on the golden "Spring Bonnie" springlock suit design seen in Five Nights at Freddy's 3 although its body is significantly darker than previous versions it seems to be more complete and less worn than in FNaF3 and now more closer resembles Nightmare Fredbear in terms of disrepair.

Nightmare Spring Bonnie's body is a sickly greenish-yellow hue, most likely from the costume's many years of use then subsequent disuse and being decrepit. Much of its artificial fur has torn and rubbed away from its endoskeleton, leaving much of its cables and wiring exposed to the elements, most likely from years of neglect and poor storage. It sports rows upon rows of sharp, metallic teeth that protrude from its head, similarly to how a shark's jaw is structured. The outer head of the animatronic suit is very dilapidated and decrepit in appearance, much of its face is obscured by dirt and decayed animatronic parts, much of this decay also being apparent over his two large ears.

Many wires have frayed from their position inside its head over the years and it appears to have lost its prosthetic eyes, revealing the cold animatronic innards underneath. Much like the other Nightmare animatronics, in the place of his normally artificial eyes are two tiny, red eyes that pierce through the darkens like lasers through steel. It also is covered in claws and sharp edges along both its hands and feet.

Nightmare Spring Bonnie's color scheme is extremely dark and muted compared to its FNaF3 version. It tends to be obscured in darkness most of the time and when in light, it appears to range from a dark green to a dirty golden brown and is consider one of the harder to see animatronics in the Hallways.

Behavior
Nightmare Spring Bonnie's behavior can be very difficult for players to follow and track throughout the house and is nearly as quick as Nightmare.

It proceeds to the Room from both entryways and if the Player goes to the wrong door three times or more, Nightmare Spring Bonnie may be seen running into the room behind the Player briefly.

If the Player is able to see N. Spring Bonnie once before it enters the room, the counter resets, giving the Player another chance to complete the night. Once Nightmare Spring Bonnie is activated, the other animatronics, including Fredbear, will then be deactivated for the rest of the "Challenge Night," leaving the player to only try and outwit Nightmare Spring Bonnie alone. Nightmare Spring Bonnie very rarely enters the Closet or appears on the Player's bed, but the player will be able to detect his movements based on the moaning sound he makes. The sound is based on the "moaning" sound his FNaF3 counterpart makes, but it has been dubbed over to sound more demonic and warped, further cementing the differences between the two versions of the animatronic.
