1) Black Tower: (Past Age)
After getting the Shovel from one of the workers in the Black
Tower, go outside. One screen south of the entrance, you can dig your
way to a Piece of Heart
2) Maku Road: (Past Age)
If you go to see the Maku Tree, take the stairs down and go west
from the room you come down to. This room has two Stalfos in it and a
block arrangement in the northwest corner. Push lower-left block up
and the lower-right block left to access the Piece of Heart.
3) Yoll Graveyard: (Present Age)
After getting the Power Bracelet, return to the entrance of the
graveyard. Go east, south, west, and south. Now lift the rock here
and take the Piece of Heart.
4) Deku Forest: (Past Age)
If you go left two screens and
south one of the Ancient Cave housing the Wing Dungeon in it (in Deku
Forest), you’ll find a small tree that can be burnt down with Ember
Seeds. Do so and take the stairs that you uncover down to a cave. Go
right until you reach the previously tantalizing Piece of Heart.
5) Talus Peaks: (Past Age)
Let’s start at the screen containing the entrance to Maku Road.
Go south twice, west five times, and pull out Roc’s Feather. Use it to
jump a gap and go north. Now go north again up a few steps to reach a
cave. Enter it. Jump across the platforms here, lifting the pots if
you’d like, and you’ll jump right to a Piece of Heart.
6) Talus Peaks: (Present Age)
Make it the past age and go to Symmetry Village. From the house
that contains the Tuni Nut, go west, south, west, north, and west.
Stand in the southwest corner of the screen and play the Tune of
Currents/Ages. Go right a screen from here, now in the present age, to
find the Piece of Heart.
7) Lynna City: (Present Age)
Go north of the Ember Seed tree. Make sure it’s the past age.
Stand so that you’re touching the upper-left corner of the leftmost
tree and play the Tune of Currents/Ages. You’ll reappear in the
fenced-in part of the shop in the present age. Enter, go north again,
and take the stairs down. Welcome to the secret shop! You can buy a
Piece of Heart here for 500 rupees.
8) Rolling Ridge: (Present Age)
Go south once of the Pegasus Seed tree on Rolling Ridge in the
past and play the Tune of Currents/Ages. Enter the cave here and take
the steps up. Walk around the path here to reach a Goron; blow up the
wall by it. Go through the opening you forced into existence and
you’ll uncover yet another Piece of Heart.
9) Rolling Ridge: (Present Age)
Go to Crown Dungeon in the present age (having beaten it) and go
right once. Take the cave to the right to its end. When you exit, go
right, north, and right. Play the Tune of Ages south of the cave
entrance here. Now slash the bushes to reach the corner of the map.
Play the Tune of Ages again to warp back to the present age where
you’ll pick up a Piece of Heart.
10) Crescent Island: (Present Age)
Go one screen north of the island guardian (the entrance to
Moonlit Grotto) so that you’re in the water. Dive down and swim right
once, north once, right again, and south twice. Welcome to the
Crescent Island underwater maze! It’s just another one of the many
secrets of the island. From this intersection, go south, west, south,
west, north twice, and into the cave. In this cave, beneath Moonlit
Grotto, open the chest for a Piece of Heart.
11) Random:
This one pops out of Gasha Nuts. Remember, you can plant Gasha
Seeds in soft soil, return a little while later, and slash the nut to
get the content. The Gasha Ring, as well as advancing in the game and
defeating enemies, greatly increases your chances of getting this Piece
of Heart.
12) Random:
Maple will drop a Piece of Heart randomly when you bump into her
in screens she appears in.
