Secret Memos are a variation of Data Files found in Pikmin 3. Unlike most data files, these do not give any tips or information. Instead, they simply have a picture of some pikmin with a number.
Miyamoto stated in a Miiverse post that if you collect all 10 of these memos the numbers in them will comanate into a Secret Code. So far, it is unknown what effect this code will have on the game. Miyamoto also stated that he will explain what effect these Data Files have later, and that we should try to keep a watch for them.
There are 2 Secret Memos per area. They are always found in the same place, but the ones you find in these places are completely randomized and unique to each player.
