You've seen this 'clothing doll' Sonic in a compilation photo elsewhere on these plush pages, but here, you can get a nice close up. This is "Hapi Coat Sonic" and he was a UFO prize you could grab. Obviously that's a Hapi Coat that he's got on, but what's that Kanji on the back? Why does he need a headband? The belt is shown to be a ribbon (from the back) while the headband is tied with a knot. He's uncommon because of the UFO prize status, but also because the get-up is kind of obscure unless you're in Japan.
