The Mystery of the Octopus in Chains

Many neat finds at the Renegade Craft Fair yesterday in SF. Also many repetitious ones. For instance, the octopus pendant with the necklace chain hooked on two of its tentacles. Three separate booths had them. Where did they get the pendants? I haven't found the answer to that yet, but did find that it is very common.

See Google's Image Search. See also on Etsy.com. Now say you really did want one of these things. (I think they are pretty cute.) How would you decide who to buy it from?
