I had a dream I knew Toby IRL and he was really protective of his files. I sneaked a peek and saw beta concept screenshots of Deltarune where Krs had a different haircut, Ralsei was the same, but Susie was replaced by like a Japanese Samurai Goroh looking guy who was just human and it was never explained. When he entered the Dark World he was the same except his skin was purple, and he had the special ability to turn into a dog. When he became a dog he had Ramb's head for some reason. There was also a part where Kris, Ralsei, and Goroh guy hung out on a speedboat with a mini-Titan, as well as some snippets of future tracks Toby was going to use including one which sampled Garfield and Friends.
When Toby found out I looked he got really angry at me and refused to talk to me for a while before admitting this character was the prototype for Susie. Then I woke up. Picrel is my attempt, not an artist
