Listener Art Form progress gif

I'm confused. Why does the Listener have 4 arms?

@ILuvHats They don't  This is how I imagined their Art Form might look like - if Art Form is even an actual thing and not made up by Venli to keep Eshonai distracted. I gave them 4 arms based off of the function art form would have - which is largely drawn from my own life experience. Usually when I create designs I try to have their form follow their function.
