One Night with Your Nightmare: Hell of Fredbear (originally created by @Neddbear502 )

Another one that was still in the works by him was called One Night with Your Nightmare: Ultimate Custom Night Revived. Nothing much was found from it besides the Gamejolt thumbnail but its somethin' I suppose.

One Night with Your Nightmare: Funtime Location (I kind of miss this one ngl):

Characters (these were the only two I was able to find):

There was one more that I somewhat remember that was called One Night with Your Nightmare: Chocolate Edition (I think) it was basically just a joke game/reskin of The Return to Abominations, I couldn't find anything on it so that game is basically lost media lol.
