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 molida island and go in the secret dig cavern you found earlier and open the door with the sun on it (with the sun key...)
You use the sun key on the sun door in the secret underground cave where you got the way to get through the fog on the island where you got the shovel.
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
The sun was hot and so was the sky. ~Dedee
