you should play the lullaby mod if you haven't! Friday Night Funkin Lullaby Mod [Friday Night Funkin'] [Mods] its based on the hypno's lullaby creepypasta. mechanics in the songs are somewhat hellish so feel free to turn them off if it gets too bad.
Bonetrousle and Song that Might Play When You Fight Sans if I’m remembering correctly. I’ll see if I can get the time stamp on a video of it
