These are the ball-jointed dragons made by CuartosDolls in Russia (at least I think it's Russia). They can be posed in almost any position thanks to every body segment having its own ball joint. Want one? Well you're in luck, because the maker is selling them, with white dragons going for €165 (~$220), and every other color including metallics for €240 (~$320).
Grumpy Cat really exists! And she's adorable!
