I have just enterd the water temple. In the corner of the temper there is a ledge that you jump on and then there is a door closed by metal bars and there also is a dark blue sign on the wall that has the "triangle" symbol thing on it.
If you check and see what Navi says about it, it says somthing about " to open the door play the song passed down by the royal family", (or sumthing like that).
I figured it ment zelda's luliby song but when I play it nuthing happends. I played it right in front of the door and also in front of the dark blue sign. What song am I supposed to play to open the door and am I playing it in the right spot?
