Your Only Move Is Modding in YOMI HUSTLE Community

What's the name of the music that plays when chaostale Chara opens a dark fountain in YOMI Hustle? (image is mod thumbnail btw)

Are there any Undertale/Deltarune YOMI Hustle mods I should try? (Undyne seven meme for attention)

this guy is ass (you can kill yourself in 3-4 moves, and he doesn't even die in a cool way. he just sits in his regular idle)
