Strange Yellow Celestia Blind Bag found

I didn't saw this one comming. This error/prototype Celestia has been found on Taobao recently. But what is going on here? There is a very high change she's just a strange protype/error that no one didn't found until now. One way to tell is because of the code wich says she was produced on 23 August 2012 wich is too long ago to be in an official release. She also has the eye design of Princess Luna, and why is she yellow?

Still after the fact that she's just a strange error, she's kinda interesting.
