It's actually laughably easy to get to this night, as there's a glitch on the main menu where if you click "Load game" before doing anything else it automatically gives you 2 stars for some reason. These 2 stars grant access to this night, and if you beat the night you get awarded your third star. However, from my understanding, nobody has legitimately beaten this night, so nobody has ever 100%'d the entire game.

To summarise the game play, you're just in a room and you scroll back and forth with a flashlight. Nightmare can appear from the table to a little beside the Golden Sonic plushie. If you hover the mouse over his face or click on him, he'll kill you, so just keep the flashlight around the bottom of the screen.

Funtime Golden Sonic will appear to the left and right, and after a few seconds he'll come closer. When he gets closer, click on him to reset him. This sounds easy, but there is no indication of him appearing and his reaction time seems to be randomised from about 1 - 3 seconds, so it's basically a death sentence if you don't get him in time. His voicelines play throughout the night, but they just play randomly and don't actually indicate his arrival.

Old Golden Sonic is exclusive to this night, however all he does is block your vision for about 30 seconds.

So far, I've figured out quite an effective strategy : Only scroll between the apple bloom plushie and the end of the table, as Funtime Golden Sonic will appear right next to those objects in his second phase.

If Old Golden Sonic appears, then just look to the right and left sides of him as you'll be able to see at least a little bit of Funtime Golden Sonic there.

Anyways, I thought I'd post about this since this is a pretty unbalanced night, however it is 100% possible as I've survived up to 3 AM (you need to get to 8 AM) so me and one of my friends have been making a little progress on beating the night.
