Either after bosses or (on twilight princess) gather five pieces of hearts.
In The Legend of Zelda: Skyward Sword, four pieces are required.
Sometimes you can also buy one or two from stores.
P.S. That is my favorite series on the planet!!!!!!!
you get a heart container
Seek up yourself a nice walkthrough on Google.
Defeat Phantom Ganon, get your heart container, get the bow, and get the forest medallion.
You get a heart peice and a shovel from him.
20. You will start with 3 hears, you get another 8 from defeating the dungeon bosses, you get a totally of 45 heart containers which gives you another 9 hearts. So 3+8+9=20
give it to that guy who is caring for the mermaid
that is not possible but you can get heart containers from killing bosses
Well if you beat the game without getting no heart containors Nothing happens
you can get your first heart container (which is like four heart pieces). Then you can go to lon lon ranch. there is a tall tower behind the horse field. There is a box pushing puzzle, push around the boxes until you can reach the crawling hole in the far corner. In there will be a heart piece. ZeldaTutor
to get a heart piece you must find it a\or beat a bossWhat he means is to get a: -Heart Piece: You must find it. -Heart Container: Find 4 Heart Pieces or beat a boss.
Type "Phantom Hourglass walkthrough" in any search engine (e.g. google). Then open any link that leads to a walkthrough but I'd recommend gamefaqs.com Or check out the related link which leads to a Heart Container FAQ by Elranzer
The Postmans Hat allows you to check mailboxes for Rupees and a Heart Piece.
