Bottom of the Well

In Ocarina of Time, Kakariko Village was home to a well. That well, as well as being the source of power for the Windmill, was the entrance to an underground chamber, in which the sacred Lens of Truth was hidden. When Link is an adult, the well is sealed, and when he is a child, it is filled with water. In order to enter this chamber then, Link will need to use the Song of Storms to super-charge the windmill and dry the well.

The well contains many illusionary walls and floors which require the use of Lens of Truth to pass through safely. At the end of the "Bottom of the Well", Link fights one of the freakiest foes imaginable, Dead Hand. However, due to poor level design, it is possible to skip the majority of the well, glitch free, and aquire the Lens of Truth in less than 10 minutes, making the only reason anybody would want to go through the whole thing is to pick up some Gold Skulltulas.
