The Legend of Zelda: Twilight Princess/Secrets

Cucco Killing
Normally in other Legend of Zelda games, beating a cucco would cause a swarm of them to start attacking you. However, in Twilight Princess, thrashing a cucco allows you to control it for a short while.

Stop Rotating Platform at Flight-by-Fowl
When you are on the platform where you land from the cannon, look on the roof and you will see one of the wind switches. Hit it with your boomerang and it will stop the rotating platform.

Get Kicked out of Hena's Shop
When you're inside of Hena's Shop, roll into things inside like the birdcage or the fish tank. After a while, she will tell you to stop. If you keep doing it, she will kick you out of her shop. To go back inside, you must apologize to her.

Fancily Put Away Your Sword
Put away your sword immediately after doing one of the hidden moves. You will put your sword away fancily, like after learning a hidden move or defeating a boss. You can also do this whenever you defeat a larger foe. Ones that take more than one normal strike to kill, or ones that are about the same size as Link.
