Some years ago I found a small (maybe just an inch or 2 high) metal Mog statue on eBay. It had a unique number, meaning not many of these were sold. I also remember finding ones of other characters. I just tried finding these again and I can't seem to find them. I must be searching wrong things, maybe some one here can help? --- Pokemon Black FC: 3955 1066 6984
Maybe you could try searching for information on the FFWiki or Amazon(dot)com.
Or, I don't know if it'll produce any results either, but you could send a message to SquareEnix's Official Webpage and get a hold of someone who works for the actual company. --- Do unto others as you would have them do unto you.
