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.
Locations
Tropical Wilds
- In a small pool in the area where the Calcified Crushblat can be found.
- Beside the holed stump that leads to the Medusal Slurker with the Juicy Gaggle.
Garden of Hope
- A Secret Memo can be found near the Elevator Platforms puzzle.
- Another can be found in the overturned plant pot that a Peckish Aristocrab hides in on the path to the Quaggled Mireclops.
Distant Tundra
- Throw a captain onto the snow wall next to the landing site. This Memo is easily visible.
- In the cave you originally had to take to reach the Vehemoth Phosbat is a Bamboo Wall that requires Winged Pikmin to lift. In a structure in the area behind it is a Secret Memo. Be careful as a Bulbear and Dwarf Bulbears are present in this area.
Twilight River
- In the second river that is reached on the way to the Scornet Maestro is a stump with a Secret Memo on top of it. It originally has a pile of Fragments on it and requires a leader to be thrown over onto it.
- On a ledge near the three Orange Bulborbs, accessed by throwing a captain off the vine path to the Scornet Maestro's tree.
Formidable Oak
- In the spotcaps behind the Reinforced Wall at the beginning of the cave.
- In the area of the cave that you must light up, is a dirt mound near a group of Candypop Buds. Use Pikmin to dig out the Secret Memo.
