These are "Animated Wings" .... Use the following keywords: idle, flutter, flutterset, flap, flapset, butterfly, and fly. Note: the animations with "set" at the end are on endless loop; if you trigger one and then another wing animation it may look weird.
Also, "fly" doesn't trigger the wings, but makes you rise up in the air in a flying pose!! Trigger "fly" and a wing movement animation together for the full effect!!
.... try it on before buying ... enjoy!
