Choose one you'd like to Voice. Remix. Replace the "ONE IN CONTROL" or "BEST FRIENDS FOREVER" sounds to your voice acting, Depends on who you voice. "ONE IN CONTROL" - Sans's Song "BEST FRIENDS FOREVER" - Flowey's Song Or literally just record and leave the recordings in the project.
Flowey - Open Sans - Open Making a Undertale Show :D need possibly more voices as well.
