Forest Training Center

From Zelda Wiki.org

The Forest Training Center is an area within the Kokiri Forest in which Link finds the Kokiri Sword as a child. The area can be entered via a small passage which requires link to crouch through. This is located near the house of the Know-it-All Brothers. The area is a small maze that houses an ever rolling rock which can damage link. The only goal in this place is obtaining the Kokiri Sword at the very beginning of the game.
