decided he wanted to do a cover of the song, making it about Stan, and when I heard his idea, I asked if he would mind if I sang it with him, which he said I could.
As for the chapter itself, I wanted to do something that showed that Wally had kept the secret Stan had shared with him fifteen years ago secret from everyone. That secret, for those unfamiliar with The Beach Bears story, being that Stan used to have Multiple Personality Disorder, and that his other half had taken advantage of other cubs, forcing himself on them.
I also wanted to explain a bit of why Stan and Birch ended up living together, as there was no pressing need to explain it before this point. Wally helping the two of them to find the cabin fifteen years ago was what I came up with, in order to be able to tie it in with the song.
More than a year after this chapter was made in this story, Dipper decided to make the move canon within the Beach Bears timeline was well, and a chapter explaining what exactly Wally did to help them was made for that story. This surprised me when I found out he had done it, but it also put a smile on my face.
