I've recently gotten into the figure series known as World of Nintendo. They have plushes and other things, but the main line includes various mini figures. Some are quite rare, and hail from the more obscure Nintendo titles, such as Pikmin's Captain Olimar figure. I got lucky and picked him up at my local Wally World for 4 bucks. Other figures have been much harder to find, though. I've only found about 6 of the 2.5 inch figures at that store and all the others in my collection have come from online sources. But my favorite prized piece of my collection has got to be the ultra rare 4 inch Skyward Sword Link.
I found this sweet deal on ebay where this gal sold me both him and the 4" Wario for 25 dollars. They came new in the box (although link's box was a bit bent at the corner). I plan on keeping him in the box and maybe reselling him if I ever become destitute lol. Although I must admit, opening him up sure is tempting. But I'm waiting on my Figma Link to arrive so I can mess with him out of the box. He has more detail and accessories anyway. By the way, the cheapest place to get him that I've found is on HLJ. So if you're looking for Figma Link as well, check them out real quick!
