Underswap - Hehehe (Sans Theme V2)

I'm on a Sans kick.

Special thanks to Jimmy the Bassist for providing the base flp that made this possible.

Underswap / IF - Dating Sans

Here's another Underswap track. Since Mettaton and Napstablook switch, I figured Ghost Fight (and other songs that use it)would be replaced with Metal Crusher or It's Showtime. Here's the first of this 3-part endeavor.

Underswap - The Happy Ghost

...You can't tell me this WOULDN'T be Snowy's replacement. Going by the common Megalovania = Bonetrousle swap, surely Sans' one other motif would take the place of Papyrus' one other motif, no?

I still have no idea who created Underswap

It's Snowing Somewhere Else

Same as Catsong, but with dogs. The replacement of the Annoying Dog (Toby Fox) is the Irritating Cat (Popcornpr1nce), so his theme has cat sounds instead of barks. But wouldn't it be weird if you fought a dog and the song was using meows? This is intended to be used when fighting Greater Dog or his swap (if there's one that's not a cat).

I can't believe I updated this 12 times. Fortunately for your feed, I only uploaded 4 of those 12 edits. I'm really sorry if I'm spaming someone with so many updates, but I can't improve if I don't know what I'm doing wrong. If it wasn't for your coments, I would have stopped in the version 0.3 (http://soundcloud.com/Demirramon/underswap-ruins-3) and it was a complete disaster. I don't think this is the final version because there are many things that still need improvement, but I hope I don't have to update this a million times more because I don't want to bother you with hundreds of versions of the same song. I wasn't even sure if I should upload this one because there aren'y many noticeable changes, even if I spent a lot of time trying to make the instruments more accurate.

But anyways, feedback and comments are very appreciated!

Also, I know that some motifs are in the wrong place, but if I move them it sounds horrible, believe me.
