How come bird Dirk's balls are always clean shaven? I'd think a Razer is dangerously big for the lil guy. One wrong move and WOOP something's gone.

He doesn’t shave them (you don’t need to worry, his balls are safe). He has hair on balls, some amount of fluff.
(Most of my arts with microDirk are messy sketches, so I often omit small details so that it doesn’t look even more sloppy).
