Love and Courage Reactor
The Love and Courage Reactor (あいとゆうき リアクター?) is a treasure exclusive to the Japanese version of Pikmin 2. It is a National Hi-Top D battery, found in Valley of Repose, where it is the first treasure encountered in the game. It is found partially buried in the same spot as the Courage Reactor in the other versions, as it is almost the exact same treasure.
Collecting the treasure
To retrieve this treasure, both Olimar and Louie are needed: start by gathering all the pellets in the area and the Dwarf Red Bulborb. After obtaining 20 Pikmin, have them dig it out of the ground and carry it to the ship.
Notes: Olimar and the Hocotate Ship's notes for this treasure appear to be the same as the ones used for the Courage Reactor, except in Japanese"
English Courage Reactor notes: “We've recovered our first treasure! Amazingly, the Pikmin remembered how to salvage it. I can't understand their adorable language and I don't know what they're thinking, yet I'm so happy to see them. When I crashed on this planet, the Pikmin helped me locate my missing ship parts. In my darkest hour, the Pikmin were there for me. Now that I'm reunited with them, I know everything will be alright. It will...right?”
English Courage Reactor notes: “Physical energy is not the only kind! The energy dearest to us is that made by love and courage.”
