Simply press the flag and listen. It ain't Rocket science. This a song from the chronicles of xenoblade, of which game shulk comes from. For some reason the people who super smash bros were too lazy to put more people from xenoblade in there. I've never actually had the game but I know enough to know there are some cool people in there. Give me suggestions of who they should put in the next SSb from xenoblade.
Feel free to use without credit- I do.
