This is, of course, batpony Fluttershy. (Battershy?) Her wings have a little snap on them so they fold up or unfold, and her tail has a wire in it that allows her to be hung from many handy perches. These batponies were the most popular thing at Bronycon and Everfree this year, and I plan on making lots more for next year's conventions, but you can also buy them at my webstore!
(I'm not having a Black Friday sale, but I thought today might be a nice day to upload photos of things that you can find for sale in my webstore.)
