Hyrule Castle
Go ahead and talk to the guard, and move back and forth between the
Market and the castle grounds until you see a girl standing by some
vines on the side of the path. Talk to her until she gives you an egg.
Now climb up the vines and jump over the gate the guard was guarding.
Move along the path until you see two guards up ahead of you...don't go
near them! Instead, go left up onto the hill. Watch out for the guard on
the hill, run behind him and head to the far left toward a cliff. You
should see some climbable rocks on the cliff, climb them and then jump
off the other side toward the castle. Jump into the moat and swim down
it until you reach the corner where you can safely climb out. Follow the
path around and you'll see the sleeping Talon. Wait until your egg
hatches in the morning and use it on Talon to wake him up and get him
out of your way. Once he's gone push and pull the blocks to dump them in
the moat. Use them to jump across to where the water comes in and climb
through the hole there. Now avoid all the guards by not letting them see
you and make your way to Princess Zelda. Talk to the princess.
