Consider: Grian plays saxophone; it started as a new way to annoy the other Hermits but he's actually gotten quite good at it. (Apt au or not, just sounds fun lol)
Combine this with my personal HC that Xisuma plays trumpet and we've got ourselves a prank duo to rival the convex! (I would say The Brass Bros but I'm 90% sure Saxes are actually woodwind. I'm too lazy to google it.)
