IMPORTANT: You will need the grappling hooks.
If you go to the student academy and find Zelda's room, it is locked. Go to the roof of the academy, West of the Sparring building, and look for the chimney. When you find it, you will see a spot to use your grapple hooks on on top of it. Grapple on a drop down.
NOTE: Look to the northeast side and at the back, you can see a Tickle doll.
