It should be a longer version until a friend of mine told me to make another OBC together. So I finished the last part very quickly.
I got lots of inspiration from DYS's version and it may sound a little familiar if you heared that version before.

Undertale: The Otherground Scrapped OST | "Jungle of Ashes", by Ethan Harper

Our first official song that wasn't by Ethan Harper! It's an incredible song, too, especially for battles! Updated several times before being replaced by a simpler song to better fit the vibe of a common encounter.

Undertale: The Otherground Scrapped OST | "Toe, to Toe, Let's Go!", by TheRadGuy

A scrapped track tossed due to its similarity with the field of hopes and dreams, which the area itself outgrew as it was further fleshed out.
Still a good song to listen to, though!

Undertale: The Otherground Scrapped OST | "Tear-Stained Heights" (Beta), by TheRadGuy

No quotes with this one. We just forgot this existed, and since it was scrapped due to being a part of the Jungle of Ashes, namely its sub-theme, I figured it would be a nice listen to those thinking about what could have been. Hope you enjoy!

Undertale: The Otherground Scrapped OST | "Temple of Ashes", by Ethan Harper

I was scrounging around some files for the game and found an old completed theme for area 1 before it was changed!

Undertale: The Otherground Scrapped OST | "The Fallen Forest", by Ethan Harper

I... Don't really know whose theme this was? I believe it was Willdmark, considering the "W." in the file name. We never gave the song a proper name, and the character in question has been long scrapped with only a fragment of what was left in them being used in another character.

Dr. Willdmark was a very... unusual take on a scientist. He was like Sans and Gaster were one character and looked like Undyne. Willdmark wasn't a very good example of character design, writing-wise more specifically, and we all tend to agree it's best we leave him on the cutting room floor.

Edit: the mystery has been solved! Ethan confirmed this theme was for Wolfgang, another indefinitely scrapped character. I won't tell anymore than that, because like Mira, Wolfgang may have a chance to be revived in hard mode's development.
