* Oh! You've fallen down, haven't you...
* Are you okay? 

* Aw, c'mon, Azzy.
* Have a bit more faith in your ol' pal Flowey...

* You met them?
* Today's just full of surprises...
* Well, I trust you're in good condition, then.
* ..I should probably introduce myself.
* Howdy! I'm ASRIEL DREEMURR, Prince of the Underground!
* Have a warm welcome to the Sunken Temple, and enjoy your stay.

Since we're in early-game territory for MT 1, why not delve a bit into MT 2 material for a bit, huh?

Mortatoriel 2, the "Betrayed Underground" ending, details an outcome in which a once-merciful fallen human suddenly kills many monsters in Cool Cool Peaks, including Grillby and Dappertune, and Queen Toriel. Former king of monsters, Asgore, has returned to reclaim the throne, trying to amend for his mistakes and reassure his people that everything will improve despite their suffering. Royal scientist Undyne has tightened security in the Underground, and monsterkind refuse to trust humans anymore. Even if humans did show some kindness in the past, anything can happen.

Asriel takes both his and Toriel's role. After his father returned to the throne, Asriel became more aware of his connection to the crown and is taking on heavy responsibilities of being the underground's prince, especially in light of the Cool, Cool Peaks massacre. Knowing well that Chara once had the promise of pacifistic humans, he secretly wanders into the Sunken Temple to watch for fallen humans so that he can guide them towards a path of kindness and compassion.
Note 1 (05/08/21): @the_freaking_weirdo has updated the thumbnail for this track with a slight tweak to Asriel's sprite; more specifically, some things hanging from Asriel's cape that were not visible (due to blending into the background with a black color) are now visible, with a dark blue color matching his cape.

Note 2 (07/04/21): Track thumbnail has been updated again by @the_freaking_weirdo.

"*FLOWEY's defense dropped to 0!"

Hello, everyone! Since it's my 20th birthday today, I chose to dedicate today and the next few days to celebrate by finishing and uploading a couple of my own songs. This is one of them. Since I'll be busy at some point today, I don't know if I'll be able to finish the other song and make it sound good all in one day without rushing things.

This was a difficult song to cover - most of the difficulties came from the mixing, volume and drums, notably in the second half, so forgive me if this cover sounds messy at points. Enjoy!

[Birthday Special/Undertale] Finale (HyperFlowey's Cover/Recreation)

Yes! Yes! Over here! I have fallen!
Indeed, it is a shock I survived at all...
Thank you for your help.
I suppose I should introduce myself.
Greetings.
I am CHARA.
...
I'm glad you like it...what's yours?

Shipwrecked is a roleshift AU that makes role changes based on popular ships. These are not necessarily ships that we believe in, just ones that have some popularity within the fandom.
I'd classify the AU as taking itself half-seriously. It legitimately has its own style and ideas, but it acknowledges how silly its own premise is.
The AU details a timeline after a botched reset by Asriel, in which he gets to be the protagonist, but no one remembers him. Not even his parents. No one...except for maybe one person...

Due to the popularity of Chasriel, Chara takes the role of Asriel.

*(Somehow, even through my control panel, I feel a chill in this patch of darkness.)
*(It feels cold. Empty.)
*(But then, I feel the presence of an invisible smile.)
*(Like a warm ethereal hug.)
*(And I feel like everything’s gonna be okay.)

Hydromix is an AU mostly revolving around Waterfall characters. Papyrus takes the role of Gaster (he is present in Waterfall on account of his phone calls).

*THE BIRD - ATK 8  DEF 2
*Savior of monsterkind, at least that’s what it would tell you.
*…which it can’t, because it’s a bird.

Recalibrated is a roleshift by @slick_silver and @dashingtoadie-the-sequel (@toadiedoesalltheworktbh). All the information that can be provided here is that the Bird That Carries You Over A Small Gap takes the role of Napstablook. It spends much of its time in the depths of a forest, protecting the lonely ex-queen Alphys.

Thanks to @unis42 for coming in with the save today!

Along with the ship swaps, there are also some miscellaneous other changes just for the fun of it. For example, Hotland and Waterfall somewhat swap with each other, so the Hotland is one big sea, hence why Papyrus is a papirate.

Due to the popularity of Papyton, Papyrus and Mettaton swap.

(Guest Track - Pluto) [Shipwrecked] No Bones About It!

Update (09/02/21): New thumbnail by @the_freaking_weirdo, hinting at the Maple Valley area.

*Please do not upload this song to YouTube and/or any of my other songs or claim it as your own. All unpermitted uploads will be reported and deleted.*

* Ngaah! What’s happening now?
* There’s been some mysterious readings over in MAPLE VALLEY…
* It’s lasted for a while...
* But it seems to be getting stronger...
WHAT THE HECK IS GOING ON?
SOUNDS LIKE A BLIGHT IS ARISING IN THE AREA!
* You think it’s something THEY can handle?
UM… WELL!
I HAVE NO DOUBT IN THE HUMAN’S PERSEVERANCE!
BUT ISN’T THIS A LITTLE TOO ABNORMAL?
THE VALLEY’S USUALLY... CALM.
IT WOULDN’T NORMALLY GIVE ME THIS UNSETTLING FEELING...

1) Yeah, we know, Undyne's first official track has yet to be revealed, but in the meantime, have a "Premonition" replacement featuring Undyne!
2) Also, Maple Valley is the "Waterfall" area replacement - it's an autumn forest valley region!

Undyne takes the role of Papyrus. Recently, she's aimed to make Sapphire Sands (the Snowdin replacement) a better and happier place, with Papyrus being the creative thinker behind her new inventions. She ended up contributing a lot more than she did in Cool Cool Peaks (the Hotland replacement), making a much bigger town in the area as well as an entire amusement park! With everyone’s beliefs and hearts beating as one, she’ll find another way to bring monsters freedom.

[Mortatoriel 1] Danger Mystery

To take a moment to properly explain the "Thirst for the Crown" collection...
Each AU will have 4. 3 will be listed as Uwa replacements, and the fourth as a Memory. They play during flashbacks that are triggered at one specific location per area. These memories tie back to Frisk's experiences in the Underground, as well as Nex's life before falling in. With that said...

Aftergore is a series of AUs taking place after Undertale's neutral endings, in which a new human enters in Frisk's wake.
Aftergore III, the Exiled Queen ending, details an ending in which only Undyne and Asgore have been killed. Toriel tried to claim the throne, but threats of a coup quickly sent her back to the Ruins. Now the Underground is in a state of instability and semi-anarchy. Humans are to be treated as...well, it's unclear right now, but it's not good.

This does not replace anything; it is an original track.

* YOU!!!
* What are YOU doing to my cousin?!
+-+-+-+-+-+-+-AU INFORMATION+-+-+-+-+-+-+-
Reunited Dreams is a new roleswap AU. However, this AU tells about what would happen if the Dreemurrs were killed during the war in cold blood. Not only that, Chara was also already part of the Dreemurr family before the war and now had grown very old. As the only living "Dreemurr" left, Chara had to find a way to resurrect their only family, albeit the prospective outcome was... rather inconvenient.

Ruins Dummy and Mad Dummy take the role of Flowey, but let's talk about the angry one here. They are extremely MAD for power and a misanthropist in general. However, they are protective of their cousin and oh boy... They are surely unhappy that a literal human just treated their cousin like a punching bag. You might wanna afford that attitude with your soul. That'd be fair, wouldn't it?
