Literally anything I can find that has to do with Underswap/Inverted Fate Sans. Mwehs and hehs. Puns and japes. Stuff where Sans is Papyrus.

UNDERSWAP - Bonetrousle

I'm so glad I can finally show this off now that the ARG is over. I slowed down the melody in Passive Aggressive and changed it up a bit to include STMPWYFS. Also, I outsourced to Keno to make it sound more authentic.

ALL comments about or relating to Chara / Storyswap will be deleted. Seriously. Not even joke comments. It's not funny.
