Just like in every Zelda game you can increase your overall health by collecting heart peices, to form a new container. There are 12 pieces hidden around the island forming 3 full containers.
Heart Piece #1
Location: Mabe Village
Items Needed: Sword
All you need to do is go to the left of town and slash the bushes on top of the cave and fall into the hole. Grab the heart piece and exit via the stairs.
Heart Piece #2
Location: Mabe Village

This fishing spot is located two screens north of the BowWow, you will see a glorious pond and a guy fishing, all you need to do is cast in and catch the fish that is directly underneath you. Do not worry if you catch the other ones first, to get them out of the way, when you get a bite, tap A fast and reel em in. #3
