Waterfall of Wishing

In A Link to the Past, a large waterfall known as the Waterfall of Wishing can be found at the northeastern corner of Lake Hylia, partway between the Witch's Hut and Zora's River. The Waterfall of Wishing is home to a Great Fairy who is known to be a friend of Venus. By swimming up the center of the waterfall, Link can access a secret which contains a small pond known as the Mysterious Pond. In the game, walking up to this pond asks if Link wants to throw something in. Any item the young hero throws in will be returned by the Great Fairy dwelling within the pond, but three certain items will be improved upon return if Link answers the Fairy's questions honestly:
 * The Boomerang will be replaced with the Magic Boomerang
 * A Fighter's Shield will be replaced with a Red Shield
 * An empty bottle will be filled with Green Potion

Ancient Stone Tablets
Level 2 in BS The Legend of Zelda: Ancient Stone Tablets is located in the same place as the Waterfall of Wishing. It contains the Magical Boomerang in the Big Chest and has two floors. The main boss is Moldorm, but even if the player falls down the hole, they no longer go to a lower floor, so they no longer need to restart the battle. At 18:34 a Heart Piece will fall from the sky and land in the shallows.
