[Holes] 15 [Location] Hyrule Field [Requirements] Bomb [Directions and Notes] 
To the far left of the castle, in front of the river, is a tree all by its lonesome. Bomb the ground right next to it. Inside the hole is a pool of water and at the bottom is a heart piece that requires the Golden Scale or the Iron Boots.
