VS already basically answered, but... Yes, it is a tinkerbat, the minions of Risky Boots, the main antagonist of Shantae. I posted an earlier version of the skin specifying a while back; since I'd already posted a version I didn't feel the need to clarify who it is this time. If you play Shantae on GBA, you can get an ability that turns you into a tinkerbat. Nearly every frame here is from that transformation, so technically this is Shantae in tinkerbat form. But I'm saying it's just a generic tinkerbat.
