Lookout Tower

The Lookout tower is one of the buildings of Kakariko Village in Twilight Princess. It's situated right above Kakariko Village, giving a great view over the village.

On top of the village you will find a little kid, Talo. You might remember that guy from the beginning of the game: he's the one who wants to be a ninja, just like Link. Anyway, Talo sees you have the Hero's Bow and wants you to show of the weapon. Do just that and you'll gain a Piece of Heart.

Inside the building you can find a treasure chest containing a purple Rupee. Outside the building you can find one Poe. A Goron is standing there as well, and he can throw you on top of the lookout tower so you don't have to get in, climb the ladder, and get out again. It's not a major shortcut, but it is one.
