Code Title: Running Man
The running man in Kakariko Village, that dashes away from you each time you approach, can actually be caught up to. To catch him, run towards him with the Pegasus Shoes. It'll take some practice, but you can catch up to him. Nothing useful happens though, he just tells you about some various things that aren't very important. Still, it's fun to be able to catch him.
Code Title: The Chickens Attack
The Chickens found in Kakariko Village and other areas have a vendetta against you; that is, of course, if you attack them. Hit a chicken enough with your various weapons, whether it be sword, arrow, bomb, whatever, and the chickens will come from all directions to peck you! It's a storm of chickens! Not really a useful secret, but a good one none-the-less, wouldn't you say?
Code Title: The Waterfall of Wishing
A fairly important secret, the Waterfall of Wishing provides Link the opportunity to upgrade two of his very important items, his Shield and his Boomerang. The Waterfall of Wishing is located at the end of the river in which you get the Flippers from Zora, but on the opposite end of the river. Pass by the Witch's Hut, move the green stone to gain access to the river, and you'll be in the general vicinity. You need the Flippers to access the Waterfall of Wishing, however. Read the signs in the area to find its location, and then jump into the water. Swim north into a waterfall and you'll be in a secret cave. Now, approach the pond in the cave and it'll ask you to throw an item into the water. Throw your Shield in the water to get the Red Shield back, and your Boomerang in the water to get the Magical Boomerang back, both free of charge.
