Hard decision between #6 and #4, but since I'm a sucker for anything with muffs and a beard, plus the added bonus of having no tail, which I also love, I'd have to say #4 for sure.
Guys, number 6 obviously! It reminds me of robot in Terminator 2 made of liquid mercury - "One ring (or chicken) to rule all others" (quote from Lord of the Rings)
