This article lists features that were only seen in videos, teaser promotions, and screenshots in the game series but were directly changed or not featured ingame.

Five Nights at Freddy's

Early Endoskeleton


In the game's Steam Greenlight and the trailer, Freddy and Bonnie's endoskeleton looks very different to the final build. Freddy's endoskeleton from the game's Steam Greenlight icon has triangular teeth and glossy-black eyes possessing red iris instead of white ones. Bonnie's endoskeleton head seen in the trailer looks almost the same.

Five Nights at Freddy's 2

Mangle with a hook

New Foxy

In the game's third teaser, Mangle is shown to have a hook similar to Foxy. Although ingame, Mangle does not have a hook and instead possesses both hands.

Original Foxy

Again in the third teaser, the original Foxy is also seen, with glossy-black eyes and glowing white pupils. However, Foxy is replaced by his previous incarnation Withered Foxy, opposed to his minor minigame appearances.

Five Nights at Freddy's 3

Unfinished monitor map

In two of the Steam screenshots before the game's release, the Monitor map is unimplemented with vent paths along with both the "Play Audio" and "Map Toggle" button.

Five Nights at Freddy's 4

Nightmare Foxy's tongue

In Nightmare Foxy's teaser, he is shown to have a long metallic tongue. His tongue was never revealed in-game, aside from his appearance in the main menu screen.

Scott Cawthon revealed in his interview with Dawko that Nightmare Foxy having a tongue makes him look not scary.[1]

Hanging Nightmare Mangle

In its teaser for the Halloween update of Five Nights at Freddy's 4, Nightmare Mangle is shown to be capable of hanging from the ceiling, similar to its original counterpart. It also sports many wires hanging off its body, like the original Mangle does. However, neither of these are shown in-game.

Five Nights at Freddy's: Sister Location

Multiple Bidybabs

In the fourth teaser featuring the Bidybabs, it seems as though it was originally intended for there to be seven Bidybabs featured. In-game, however, there are only two Bidybabs at most, at any given time.

Bon-Bon in the vents

Bon-Bon is shown crawling through the vents in the first teaser for Sister Location's Custom Night update, but he never does so in-game.

Five Nights at Freddy's VR: Help Wanted

Wrong-colored Nightmare Fredbear


In the first trailer and one of the screenshots before the game's official release, Nightmare Fredbear's model seems to have textures resembling Nightmare Freddy, lacking his buttons. This was fixed later on during development, due to a trailer needing to be released as soon as possible.

Spring Bonnie


In a few promotional images for the game, of the game, Spring Bonnie is shown as a part of the animatronic amalgamation. The original Spring Bonnie doesn't appear ingame. A malicious software in a form of a grinning rabbit suit is a counterpart of Spring Bonnie, named Glitchtrap.
