I got them off eBay.
I think they probably cost around €15, including post & packaging...
One of the Link dolls hands doesn't stay on though... very annoying. but they where unopened. The traders on eBay have lots of them
They are originally from these little capsule machines that you get on the streets outside shops in Japan. You know the ones that give you utter junk here... well in Japan they give you cool stuff. There is a series of Animal Crossing ones as well.. and I just got a bunch of Evangellion ones.
Hobbes, I really like that Plush Cthulu. I found a website that does them: http://www.entertainmentearth.com/
Is that where you got it?
