I've seen some like that, I went to IDEX back in 08', that's like one of the big premier doll and bear shows in the US. Some of the baby ones are pretty, but some of them scare the bejeezuz out of me. There were some silicon ones that I thought were gonna come alive and eat me @_@;
Mine are all made out of resin, and they vary in sizes. I think my smallest, Clover, is 28cm, and my biggest, Blizzard, is 65+ cm. Blizzard is a limited edition as well, one of 100, with a robot/android esque body. I also have Efala, who is the same size, which is an elf, Nimbus, who is 45cm, and another one who is 60cm, but I haven't found an appropriate name for her yet. Usually they get names based off of my personality and subconscious, but some take longer than others to figure out.
