Easter eggs

There are easter eggs and rare screens in all of the games in the series. Some of them add to the story. They are often shown as hallucinations. For example, in the first game, there is a character named Golden Freddy. In the second and third games, there are eight-bit minigames, in the fourth game there are random items near the bed, in the fifth and sixth games there are blueprints, and in the seventh game, there is a minigame called Princess Quest.

Closings

The player's location closes soon after the end of the first, second, third, fifth, and sixth games. In the first game, it is said that the place will close by the end of the year. Because of "a tragedy that happened there many years ago." In the second game, the place closes because the animatronics are broken. In the third and sixth games, a fire causes the locations to close. The fifth game, on the other hand, is different because the restaurant where it takes place, Circus Baby's Pizza World, closes before the events of the game because of a gas leak.
