We FOUND the song by the lake!!... in Chapter 5...

Original song is called ch5_inversion_lake_chant from Deltarune Chapter 5 Enjoy my poorly created creation, Princes and Princesses and neithers! I really, really don't like wasting your time. That's why I tried to make this video as short as I could while keeping my motivation active. Alas, I settled at 4 minutes. Definitely could've been less than 3.5 minutes. Oh well...
