On the island where you got the shovel. When you go down the secret cave underground in from of that tree and begin to exit, you will see the sun door.
you will have to beat the sun temple.(temple of courage)
There's no Sun Temple in Phantom Hourglass. There is a Sun Key which will be used for multiple things, but there is nothing in it that I know of (and I've beat the game) that is called the Sun Temple.Sorry.
In the temple of courage, which is in the sun temple on the island to the south west of the starter island.
To get into the temple you need to find the three stone heads and put theire beam on the eye at the door of the temple of courage.
you got to be fast and get to the sun temple and find the hidden room that takes you to the place of the fairy and she will help you with the rest of the stuff and that is how you win it
take the second passage way and use the sun key to open the door
U touch it
You use the salvage arm.
in town dig in front of a palm tree somewere by the mailbox but to get past the door with a sun on it you will have to get the key first!!!
im pretty sure u use the sun key somewhere in the depths of the ocean kings temple and the ghost key in the lvl with the 4 girls
After you have gotten the sun key, sail to Molida Island and use the key to open the odd door with the sun crest on it (found by digging underground). This leads up to the Temple of Courage.
go to a certan island called.. oh nos! i forgot but! when your on the island go to a tree then dig then you fall then go to a door with a sun picture then yuse your sun key then go thu then go to temple then point some statues to a door then you discover a new temple!
