In the original game, the song "bopeebo" uses  this scene below: (the first) 

And the song "south"  uses  this scene below: (the second) 

Question:

I want to use the second scene when playing the song "bopeebo", how to do it?

In other words, how to change the song for a scene？Or how to change the scene for a song? 

All three statements have the same meaning.

Thanks very much!

Maybe try asking in the FNF community, that way someone who knows about the project can help you.
