The Iced Donkey is an aqua-colored frozen Donkey, standing atop a small mound of snow. Of course, if you have your land covered in snow, the base of this decorative item will blend right in, adding to the "realism." You'll be able to receive these Iced Donkeys as gifts only as long as it is available to send from the free's gifts page (if this is anything like the other "Limited Time" gifts, it won't last long), so make sure to ask your friends to send you one now, rather than later, to ensure that you don't miss out on the item entirely.
Have you created your own ice item collection in FarmVille? Which of the Iced Animals do you hope Zynga releases next, and how? Let us know in the comments.
