Collecting dancing mice

When I started this page I did not have any stuffed mice and now I have or will shortly have four through Ebay. The mice are important in the Nutcracker so I suspect there are quite a few more out there. What I would really be interested in knowing would be about such "mice" from other countries, especially Russia.

I am sure this mouse is from a story, but we can't think of which one, but if you have kids, I am sure you will recognize her!! (and if you do, let me know!!) She is a white mouse, cloth doll, dressed in a pretty pink ballerina outfit. She is about 9 inches tall if you don't count her ears!! 3.00
