"Mrmm. A song that never ends... is no song at all."
-Brumm

Name: Nymm
Location: Dirtmouth
Nymm is a bug who arrives in Dirtmouth after the Grimm Troupe is banished. He plays an accordion-like bug to bring cheer to the fading town, although he admits that even his song is a little on the sadder side.
"I find the place a little melancholy, what with the wind, and the darkness, and the sense of decline... I was hoping my music could go some way to livening up the place."
