Welp, I adored that character design because I'm a big nerdlinger, and I happened to have an almost-finished yellow pony laying around, so I made a Flutterbat plushie. I decided to to list her on eBay
because I'm currently saving up for plane tickets so I can go see my brand-new nephew back in the states, and any little bit helps. I've started her a low price and the shipping is free!
There's some more views of Flutterbat here.
She's about 7 inches/18 cm tall (a little taller if you count the ears), with a fleece body, yarn mane and painted features. Her hooves are weighted so she stands solidly, and her wings are wired so they can be posed.
