Bottom of the Well

In Ocarina of Time, Kakariko Village is home to a well known as the Well of Three Features. It is the the entrance to a dungeon, known as the Bottom of the Well, which contains an underground chamber that guards the sacred Lens of Truth. When Link is an adult, the well is sealed, and as a child, it is temporarily filled with water. In order to enter the dungeon, young Link has to play the Song of Storms to Guru-Guru to super-charge the Kakariko Windmill and drain the well dry.

The well contains many illusion walls and floors which can only be identified as fake using Lens of Truth, while in other places floors are invisible requiring the Lens of Truth once again to reveal such illusions. Deep within the Bottom of the Well, Link fights one of the freakiest foes imaginable, Dead Hand, which will yield the Lens of Truth upon death. However, it is possible to skip the majority of the well and acquire the Lens of Truth in less than 10 minutes, making the only alternate reason anybody would want to go through the whole thing is to collect the Gold Skulltula Tokens.

On the whole, this dungeon is completely optional, having no effect on the plot or completion if not attempted. However, without the Lens of Truth, not only will the last two temples and Ganon's Castle be of immense difficulty, Link may miss out on many hidden Heart Pieces and treasures only the Lens of Truth can uncover throughout Hyrule itself.

Concept
As a dungeon, Kakariko Well is unique in many ways. It has three basement floors, but only the first and largest one is required to explore; as a matter of fact, Link only reaches the third floor after accidentally falling into any invisible hole. Notably, this last floor is hand-shaped, and when Link falls into one of the holes, he lands upon what's apparently the extreme of one of the fingers of this hand. The only way to climb up to the first floor again is by collecting silver rupees (for the first time only; after that, Link simply has to climb up to the highest-placed door). The second floor is the smallest, as it's actually the result of the descended level reached by some other holes.

Master Quest
In the Master Quest version of Ocarina of Time, the Lens of Truth is no longer useful in the dungeon, because all fake floors and walls are now visible to the naked eye. The reward for fighting Dead Hand is the compass, though a Small Key is found in its room. The Lens of Truth are now found on the bottom floor; the one with poisonous water, which is now full of boulders, a Wallmaster, and five ReDeads all together. The Green Bubble is now missing, as well as the Like Like and the Beamos. The room with coffins and Gibdos is optional, too, containing only a Gold Skulltula. There are some hidden switches in the walls that unlock doors or drain the well; playing Zelda's Lullaby in front of the statue unlocks some gates now. The new enemy here is a Floormaster.

Trivia

 * According to the old man in Kakariko Village, the house of a man who could see the truth once stood on the location of the well.


 * The Dead Hand mini-boss that guards the Lens of Truth is possibly the same mini-boss fought in the Shadow Temple for the Hover Boots, although in his second appearance, or the new Dead Hand's first appearance, the Dead Hand possesses more hands in the ground than in the previous encounter with a Dead Hand in the well.
 * It is strongly believed by Team Beta Triforce as well as the Zelda hacking community in general that the Bottom of the Well was at one point the Hyrule Sewers which Link needed to go through to get in and out of Hyrule Castle in the beta.
 * The Clock Tower interior in Majora's Mask is similar in atmosphere and context to the main area of the Well.
