Nyarth's Ballad is the 7th song used as part of the Pokémon XYZ Character Song Project. It replaced The Squishy Song for a couple of episodes.
The moon is out at night as the clouds slowly pass by from the view of Nyarth sitting on a tree stump as he plays a guitar. Musashi and Kojiro walk up and sit being Nyarth as he sings. Wobbuffet, Inkay and Pumpjin also appear and sway back and forth as they listen.
