If you haven't quite had enough hype from The Legend of Zelda: Breath of the Wild yet, then fear not, your 3DS has a fun extra waiting for you. Nintendo has distributed a special guest into the StreetPass Mii Plaza through StreetPass - Eiji Aonuma.
He's in his golden pants, like all of the special guests, and rather humorously his message is "Let's get Wild" - he's a feisty one. Naturally Aonuma-san also has all of the puzzle pieces, because he's awesome like that.
This Mii should be waiting for you on your 3DS, so check it out.
