Bonnie's 1 remake originally had a mode called Nightmare Mode, this mode was removed from later versions of the game, but this mode can still be found in the android port of the legacy version,
now from what it sounds like, it sounds like a hard mode of the normal nights, but thats not true, it's instead Fun with BB from Fnaf 4 but seemingly luck based.
You are only given a minute and a few seconds to get Nightmare BB on the X, except sometimes it just doesn't work and you die anyways.
(Another fun fact: This mode was actually reused from Five Nights At Bonnie's Chapter 1 Remastered, only difference is that it was called Night 7)
If you completed this mode, it would give you a forth star which was also removed from the later versions.
That's all I have to say really.
