Warning though: spoilers.
go to the beach, if you've completed mostly everything, you should see three of the four guardians. Click on them, and they will say things then engage in a fight. After the battle, it is revealed that sunstar isn't dead! Then a car will fly in the sky, and sunstar will call it a shooting star and tell you to follow it. Go to the mountains, and the car will have destroyed the cave closed off with a padlock, allowing you to enter the dark.
