Webkinz are now in Russia! This is the official site. I discovered them the other day at Dyetsky Mir, the main children's store in Russia. I was surprised that they're only 400 rubles; that's $13.33, pretty much what they cost in America!
Anyone can play in Russian; you just choose Russian from the language menu. This could be a great way for older adopted children from here to maintain their native tongue.
