Quality is not a considered factor; if it's a Sans Bonetrousle at all (or "Sanstrousle"), then it goes in. Period. If you find any I don't have in this playlist, send them to me in a Discord DM (dexiedoo_octo). Rules below.

NOTE: "BONE ATTACK" by Miles Torres is stolen. It is actually by MrSebas on Youtube, listen to the original upload here: https://www.youtube.com/watch?v=npnOgILjU-o
I am keeping it here as MrSebas has never uploaded the song to SoundCloud.

To clarify, this is not just Underswap. Any AU where Sans takes on the role of Papyrus is fair game, and songs that replace the Bonetrousle functionality are what count.
In a case where only a Nyeh Heh Heh equivalent is available, I will include that. If a Bonetrousle version of that Nyeh Heh Heh is released, it will replace the corresponding Nyeh Heh Heh track in this playlist.

The playlist is sorted by AU:
- Canon and Fanon Underswap
- TS!Underswap
- Misc. Underswap Takes
- Swapswapswap / Tripleswap
- Inverted Fate
- Misc. "Sans as Papyrus" AUs
- Underswap Combo AUs
- No AU

Every Single Sans Bonetrousle/NHH

Megalovania 3

Get it done

Undertale au stuff... but no creepy shit

Every day I’m trouslin’

NOTE: This is a for-fun Megalo based on a Classicswap interpretation of Aftergore + Underswap. It should not be associated with the higher effort Mortatoriel, which can be found here @mortatoriel-official

HUMAN, YOU REMIND ME OF SOMEONE I ONCE KNEW.
IF ONLY YOU HAD THE KIND OF HEART THEY DID.
WHICH IS TO SAY HAVING ONE AT ALL.

Wonderful thumbnail once again by @shinyemerrald

While most motifs here are obviously by Toby Fox, it features REANIMATION by @keno9988v-official and a little bit of DYSMORPHOVANIA by @junnboi-the-fourth!

Mortatoriel is the "official" name of Underswap + Aftergore. It's not something we'll be pursuing much though. This was made as the one year "birthday present" to SPEICIDE, which came out one year ago today. While this doesn't religiously subscribe to any take, we did this with Tonyswap in mind, with a few extra references in there (mainly REANIMATION) just for good measure.

If you're curious about name: SPEICIDE meant "killing hope," and CONTRAMORPHEUS means "against dreams," so that we could swap hopes with dreams. Latin is fun.

While we're not exactly "Megalo people," we can't deny the tremendous impact SPEICIDE has had on Aftergore and our account. Our account has over triple the followers it had at this time last year, and SPEICIDE is what put Aftergore on the map for a lot of people. We thank you to everyone who has supported us, and there's plenty to come in the future! If you're new to Aftergore or to this page, know that while we have nothing against Megalos, you won't find much in the way of them here. Nonetheless, here's the Aftergore Discord if you're interested! https://discord.gg/WbzykND

Hey, this time it ain't that empty! Let's go!
Anyway, hey guys, I had the bright idea of remaking the us!Sans Trousle quite some time ago, but I never really got the chance to really execute it, so here I am now, bringing you the remaster of it. Enjoy!

Undertale OST © Toby Fox

I decided to go through the Undertale OST and learn/record things on piano. And the ones I'm uploading here are the "highlights", I guess? Or more the more popular tracks from Undertale/the ones people request for me to put up here I guess

Apologies for any moments of messiness or non-smoothness while playing these, I was mainly just looking to go through them without spending double the amount of time recording them in order to get The Most Perfect Take, haha

I actually have my first album coming along at some point in the near future. Hopefully that's exciting. It's FNAF, though, so it may dissapoint some of you. I hope not, though. Nevertheless, hope you enjoy this Undertale song.
