So these animated furs whatever they may be, would be available for a limited time. These furs won't be active forever either, and will be fairly rare. With exception to whatever game modes/shaman art (if any) in the future. And to clarify, these furs would never be purchasable for permanent use.

One example for an animated fur that can be in your inventory, is the Christmas tree fur, except this Christmas tree would have blinking lights and an animated aura surrounding the star.

An example of a non-Inventory fur is Coal Dust. This could be a Present in Christmas events, so instead of getting something in inventory you get coal, room chat will display "(your name) has been naughty" and your mouse automatically gets a coal coated fur, that leaves a dusty trail everywhere you go.

Lol. It sounds cool and funny. /support
But how would you get naughty?

I like the ides of this it sounds fun, although the only problem is that it would be very difficult for them to make this happen because it requires a lot of coding and such into the game.
