DELTARUNE Chapter 2 Secret Boss Full Walkthrough and Fight (Pacifist)

Here is a full walkthrough on how to fight the secret boss of the chapter! As far as I know you can fight this boss at any point as soon as teleporting becomes available. Supposedly you also must be Pacifist during the entire playthrough, I am not sure if Chapter 1 is counted towards this progress as well (my chapter 1 was pacifist but i do not have the secret boss beaten).
Overall It is certainly a more complicated process vs Chapter 1 secret boss but this fight least to me feels easier (my first time fighting him here). Any questions about any part of the process lmk and ill try to respond. Enjoy and good luck to those who are eager to tackle this boss!
