"Interesting. VERY interesting."
This video details one of the (in my opinion) most unknown yet most cool secret in Undertale: the hidden melody in "snd_mysterygo", which plays when interacting with the Mystery Man inside of Waterfall's secret room (and one of Gaster's followers in Hotland).
Please ignore the minor errors, like how "who" should be "whom", for some reason I always notice them as soon I've uploaded and not before!
I discovered this secret from this video. It's one of the most informative videos I've ever watched about Undertale, and I'd give it a view if you're at all interested in Gaster in Undertale or Deltarune: [ Ссылка ]
The Mystery-Man footage originated here:

In a few days, I will be uploading a big video, which ranks every Undertale song according to a poll I held earlier this month (which received over 1500 responses!). It's pretty interesting, so stick around if you're interested!
