Do you remember the different "Seasonal" plushes from Japan Plush Page 1?
Here's a nice close-up of the Tails from that set with the drum in it. This is obviously some Japan only occaision. Tails is normal, and cute, but he has on some sort of red vest thing with a yellow ribbon belt. He also has on a twisty-rope head band (it has slipped down in this photo) His bangs are semi-3D and look to be made of thick felt of some kind. It is interesting to see this doll up closer.
