UNDERTALE: Second to Last Breath

UNDERTALE: Second to Last Breath is a parody AU of UNDERTALE: Last Breath. In it, the Sans is actually the second to go through a Last Breath sort of thing and he's not quite as sure what to do as the normal Last Breath Sans. It has way more official phases than the real Last Breath, each more ridiculous than the last, which is an obvious joke at fanmade phases going into the thousands at this point.

It's mainly a musical AU which is accompanied by a sprite of Sans and whoever's with him and some dialogue next to them, as well as a bit in the descriptions.
