The Baneling is a critter from StarCraft that causes all sorts of problems by exploding on you. Despite this; they remain something of a fan favourite and it was only a matter of time before we saw them on Etsy.
Sorry, if you were looking to buy from this BoRoShan then you’re out of luck as it’s sold. Hopefully more will be made. It’s worth checking around the rest of BoRoShan’s stall as there’s some good stuff there.
