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

In Destiny Neat, we will follow the journey of Jadsen, a monster from the surface, crossing the magical barrier that protects humans from monsters, discovering a new world hidden within the mountain.
In this version of Underswap, we will face the various bosses from the original Undertale, but in the reverse order. There are really only two essential changes for this version:
Asriel Dreemurr < - > Chara Dreemurr
7 Human Souls < - > 7 Monster Souls
Our protagonist wants to know the truth about the monsters and their fear of humans, but this time he will not do it alone, 6 special young monsters will accompany Jadsen and together they will find a way to break the barrier so that the monsters and humans can live. in harmony.

Protagonists:
Jadsen - A goat monster with huge DETERMINATION to free the monsters - Red Soul
Boogie - A ghost monster, being the younger brother of the Blook family, he is very shy, but has a great mind, being able to strategize during battle with a little PATIENCE - Cyan Soul.
Boris - A bully spider monster that we will encounter before entering the citadel, he is rough with others, but with BRABERY, he will protect his friends like a good defender - Orange Soul.
Noel - A kyubi monster from Hotland and friend of Lidsey, she has great courage as a fighter and she's persuasive with others, she always finds a reason not to fight, with JUSTICE she will find the solution to problems - Yellow Soul.
Lidsey - A cat monster friend of Noel, she is a fan of the Mettaton show, among all of them she has the most magic, since she is a magician as a hobby, although she is happy with others, they do not think the same way, but they don't know She lets herself get carried away with the criticism of others, she has PERSEVERANCE to move forward - Purple Soul.
Lilith - A dragon monster being a recruit to the Royal Guard, she will chase us throughout Waterfall, before Boris and Noel are captured, they come to her senses and she decides to support them and have INTEGRITY with her choice - Blue Soul.
Jack - The Boss of Temmie Village, the most intelligent of his species, he always takes care of others like a good healer, he seems like a bitter monster, but there is always some KINDNESS in his heart - Green Soul

Main characters:
Flowey: The same Flowey we meet in Undertale.
Asgore: The King of the Underground and protector of Home and his citadel.
Alphys: The Royal Scientist, she is curious about Jadsen, so she tests her will.
Mettaton: When detecting a "human" soul, they changes his mode to Eradicate Humans for Jadsen's soul.
Undyne: There are no major changes, being us a surface monster, she will stop us from advancing further.
Papyrus: He was finally able to join the Royal Guard and as his first mission, he will stop us at all costs with her puzzles in Snowdin.
Sans: A bodyguard of Queen Toriel, he is the same as always.
Toriel: The Queen of the Underground, she always visits the city that the monsters moved to long ago, New Home, currently she is with her bodyguard resting in the old Dreemurr cabin.

Name the fallen human

Leitmotif:

Yep, Frisk is still the first fallen human here! You play as Chara. On the other hand, "Determination" swaps with "Hope". Which means, "Hope" is the core trait of every human being. Chara benefits a lot of hope and possesses the soul of "Courage".

☂ An Empty Stream of Progress ☂

*Long since, two races reigned over the EARTH: HUMANS and MONSTERS.

Leitmotif:
- Ruins(/Battle Against a True Hero)
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Since it's related to the intro, the barrier swaps with the gate entrance from the Ruins, and Mt. Ebott swaps with Mt. Emmett (which is actually real mountain if you search it up =P)Like Toby's old plan, Chara's going to seek for a refugee from a heavy rain outside, which explains why it'll be raining in the sanctuary. Chara will be donning a cute green raincoat and bring an umbrella as a... weapon.

Third update! Remember the very first version of "Left in Ruins"? Yeah, this is a combination of the two which additionally uses genesis soundfont to stay consistent with the technical SEGA and Nintendo swap.

☂ Left in Ruins ☂

"   * right, let's get this show started.
     * sorry kid, nothing personal.          "

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!

Majortrousle (Bonetrousle in a Major Key) - Undertale Cover

I figured that, since I just uploaded a new Undertoad episode, I should update one of its first songs. This one is also longer because it's the Trailer Version.

And yeah, I DID reach 1000 followers! The special for that is going to be an original song though, so stay tuned.

Undertoad - L-Trousle v2

note: school started, so expect less frequent uploads. like, maybe once every other weekday, and *maybe* sunday and saturday if i feel like it.

and, if you are going to upload this to youtube or anything else, first, ask me via DMs. and use the most current version of the drawings, please. and i suggest you delete any videos you may have made for the old version as well.

this is the new version to keep it up to standard with the other songs. the old one is going to be deleted in 3 days. so say your goodbyes to the older one i guess.
