Nintendo's Shigeru Miyamoto has revealed the secret behind Pikmin 3's hidden memos.
Miyamoto previously teased that he had scattered 10 hard-to-find video logs starring original Pikmin protagonist Olimar within Pikmin 3. Collecting them all provides a mysterious 10-digit code.
"As promised, I'm here to tell you how to make use of the special code you've obtained if you've managed to find all 10 of the secret data files," Miyamoto wrote on Wii U social network Miiverse (thanks, NeoGAF).
"During their latest treasure-hunting adventure, Captain Olimar and his Hocotatian crew recorded a series of secret Expedition Logs, and entering the special code allows you to access them! The secret data files are hidden in various locations. If you haven't yet found them all, don't give up. Keep on searching!"
Miyamoto then directed users to nintendo.co.jp/pikpiksecret (which you have to view via the Wii U's own internet browser).
Enter your code there and you'll be rewarded with a video log from Olimar. At least five versions have been discovered so far, and helpfully posted online by GameXplain. You can watch them below.
