Carben

Oh, are you ready to go to the Ocean Sanctuary? Yes. No.

I'll be waiting for you in the train.

Hm, what's this? I thought you said you needed my help!

Ah, we finally made it. It was just a short distance away, but it felt so far. I suppose mortal peril has that effect on a person. You really must be more careful in the future, Link!

Here, this is for you. ...You look confused. I'll explain, Link. Every living being possesses an energy... And this energy is similar to the energy that powers the Spirit Tracks. When a person's heart is especially happy or grateful... His energy levels become particularly strong. Energy lives in the hearts of everyone, even feeble old fellows like me... I don't express it well, but the bottom line is that I appreciate your help... Here, please take this. It belongs to you.

You plan to continue your journey by train, do you not? Then you must always go forth with people's hearts in your mind. When you make people happy, their spirits emit energy. When this energy builds, new tracks appear. This should be very useful for your journey. All right, I'll be heading out to the sanctuary now. See you!

So...you are actually looking for something, yes? Yes. No.

But of course. You've come all this way, so I'll do everything I can to help. Very well then... In order to restore the tracks, I'll need your help. You do know about Lokomo songs, don't you? Yes. I forget.

This song requires two different instruments to play different parts. I'll teach you your part first, so listen well. Just copy what I do. Once you've had enough practice, you can put down your flute.

They're special songs that you play to restore the Spirit Tracks in each realm. Each instrument plays a distinct part, and combining them creates a song. I'll teach you the song for this realm, so listen up and do what I do. Put your flute down once you think you've got it.

What? Are you twisting my wheel?

Thanks again for earlier, Link. Let me reintroduce myself. I am Carben, guardian of the Ocean Realm. You're here to restore the Spirit Tracks, aren't you? Yes, I am. Nope.
