The Sugarble Medusa
Kim Jiae has been working on this 26 cm doll (when she has legs) for quite some time--it's worth reading the work blog on the Sugarble site to see what she went through to get the tail to move properly, and to make all those tiny, tiny scales.
Although Medusa is too small to come live with me, I keep thinking (probably because I have been making hats) that she would be the Most Awesome Hat Decoration Ever if you were constructing a big elaborate hat. Maybe with a Garden of Eden theme. Or a lot of stony Greek sailors. It would be heavy, though. :D
