here's the stage

They're on edge enough that it doesn't hit them, mothwing-dash back out of habit (tried and true for dodging actual Belfly threats).

Just as quick, they're back and plucking it from the film of water it landed in.

One of Lemm's cleaning cloths, obviously, and for their Nail, just as obviously, though they don't need it.

Something is a little odd about the texture. They squeeze it lightly between their claws. It's damp, but from something more than the water?

(While they know what it is, the idea of polish sails straight between their horns.)

They retreat to where the rain can't reach them so easily and start to clean.

...Lemm might get a somewhat-shredded cloth back.
