First, let's head back to Sahasrahla. When you talk to him he'll tell you
stuff about the Pendant of Courage. Then he'll give you the Pegasus Shoes.
Now you can dash! (use the R button) He'll also tell you to find an item on the
east side of Lake Hylia. Let's do that. First, make your way to the exit in
the south (dashing makes things go faster). On the next screen go west, then
cross the bridge and head west again to Link's house. Now if you used your
medicines or fairies follow this. Otherwise, go to the next paragraph. Go up
to Link's house, then go west a screen. Dash into the pile of rocks to find a
secret area. Inside is four fairies. Holy crap, it's a fairy fountain!
You'll find these in various places in Hyrule. Bottle one or two of these
fairies with your bug-catching net. Now back to that item.
