UndertaleSans is.... Parody

This looked better on my computer... My biggest regret. AU: Underfell and Underswap (So you guys won’t pester me about this.) pls don’t upload this anywhere without me or my sister’s permission, i beg u fam pls.. The original video, I believe is the Touhou one? And the song is also from Touhou called “Phantom Ensemble“ which is remixed from what I heard. There were a lot of drawings that wasn’t in the video like: - Sans in Frisk’s outfit - Sans dancing on that meme thing - Lost footage - Gaster Smoking
