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

4. Morning, Friends!

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
