Things You'll Need
Instructions
Travel to Lake Hylia in Link's child form, the only form that can plant magic beans. If you have already begun the Water Temple, play the "Serenade of Water" on your ocarina to teleport there immediately. The notes of the song are "A," "down-C," "right-C,"right-C," "left-C."
Run to the house at the edge of the lake and locate the patch of arable dirt along its wall.
Stand over it and use a magic bean, which causes Link to plant a seed there.
Go to the Temple of Time and draw the Master Sword from the pedestal to become an adult.
Return to the house in Lake Hylia and step on the large plant that has grown in the time since Link was a child. It will move upward, allowing Link to step off and take the Piece of Heart.
