Five nights at Freddy’s is a media franchise that includes games and movies. It’s a horror story about a pizza place that has teddy bear like robots who are also ghosts of children.

It is or was popular among preteens for a while. It’s somewhat similar to Poppy Playtime, with the characters being used all over tik-tok and Roblox etc.

I have no idea nor desire to know how it makes any sense as porn, or why any adult would even want to create that kind of content.
