???: Oh!
???: Greetings, beyonder!
TILLY: I'm TILLY! Tilly the dog.
TILLY: ...
TILLY: Mate, you know it's pretty dangerous here, right?
TILLY: Well, it's lovely seeing you here regardless!
TILLY: I suppose if you're going to be the one to free us,
TILLY: A little tutorial wouldn't hurt, would it?

Tilly from Double Life is Flowey. Yes, Jimmy is no longer Asriel, rather he takes a role I think is arguably more fitting. The actual Asriel replacement for BTWB2 might be pretty obvious already, but I'm going to make the reveal as painstakingly drawn out as possible (the asriel replacement won't be revealed til Track 71 drops) s'yeah.

The implication here is that there's civilization beyond the World Border, yeah. Though what that is can be left up to interpretation.

Relevant roles:
??? - Frisk
Tilly - Flowey

BLOOP -- 20 DMG 20 APT
This golem's iron punches will knock the socks off anyone who dares oppose it!
---
This song is practically made exclusively with Iron Golem sounds (with fainter note block sounds). I made the soundfont for the iron golem noises myself.
Bloop (from Wild Life) is Greater Dog, naturally, since Big is Lesser Dog.

28. BLOOP SMASH!!

* Sup. You must be the outsider or whatever, huh?
* Eh, I don't really care about people like you.
* Name's Nora. But people just call me the "Smoking Zombie".
* I guess that description isn't entirely incorrect, though.
---
The Snow Fortress from Last Life is Snowdin Town. About time it got a track, seeing as the "Snowy" replacement is the oldest track in the entire OST. I won't have much to say for either of these 3 songs, there's not much plot-wise here I think that wasn't in the original game in some form
Meanwhile Nora's a recurring minor npc, you'll first see her in the Snow Fortress.

IMPULSE: Another player...?
IMPULSE: Nevermind that, welcome to the I-Shop!
---
Impulse (ImpulseSV) is QC, or the Snowdin Shopkeeper. There's unique shop themes for each one in the game (there's 4, just like in base undertale)

30. Negotiation

* Vwoop vwoop.
* Woop woop?

The Titanium Egg base from past life takes the role of Grillby's restaurant, and BigB is Grillby himself.

[ Jimmy chucks an unavoidable blue feather into the SOUL, which then grows wings. ]
JIMMY: AHA!!
JIMMY: And there we go!
JIMMY: That's my ultimate technique!
JIMMY: You have WINGS now!
JIMMY: Good luck learning how to fly through my attacks!

* You've got wings now.
[ ACT ]

  * Compliment
  * Insult
  * Joke

JIMMY -- 22 DMG 20 APT
Nothing seems to go right for this canary. He'll have a great friend in you. Well, if he survives.
---
Jimmy (SolidarityGaming) is Papyrus. This track plays in his boss battle at the end of the Snowy Tundra. He proves a surprisingly difficult and competent opponent, after being practically completely ineffectual through the whole Snowy Tundra. I'd say it fits better than Bdubs (the V1 Papyrus replacement), especially relationship-wise.

The blue soul is the default soul, so all of the bosses instead do other modifications to it akin to Undertale Yellow, rather than outright changing the soul color. The one here is flight, where you can 'dash' and fly through specific attacks (which quickly drains the flight meter. If it runs out you can't fly).

Jimmy has the most powerful lightning attacks, being a four-time canary compared to everyone else (who was out first once) but he actually uses them fairly rarely, and mostly only to catch the player off-guard.

Also haha friend inside me in the beginning (it actually kind of fits, if you know empires smp s2)

Something big is coming.

This is for my Minecraft-related Undertale AUs Achroma and Alphabright (for the web series "WHITEPINE") and Behind the World Border (for the Life Series). 

It will also hold miscellaneous Minecraft tracks of mine, not belonging to either of those two
