Octillery, a Gold/Silver-era Pokémon who we had to look up just now (because we've never seen or heard of it) is the focus of a new promotion at Japan's Pokémon Centers. Between November 23 and December 9th, Diamond/Pearl players can bring in their level 65+ Octilleries (called "Okutan" in Japan) and receive a special Octillery sticker, seen above. It's a pretty nice promotion and a nice piece of art for this octopus-thing, we think.
This isn't the first limited-edition Octillery item. The Tokyo store gave away Octillery headbands to high-level Octillery owners in July. Is this a popular Pokémon or something? Is it the jaunty headband?
