I was doodling gremlins in class today.
Was thinking of gremlins' culture and stuff. Figured that they'd probably have clan/family crests or something. maybe military(mechanics?) badges or something. Gear motif on the outside, measuring their success and skill with the number of flanges (I dunno if that's what they're called).

The one on the bottom has a gremlin double revolver. It's sort of impractical, and it uses two chambers, one to feed the other, and the other to fire the rounds.
