Stone Tower Temple

The Stone Tower Temple is the fourth dungeon in The Legend of Zelda: Majora's Mask. In this dungeon you are able to obtain the Light Arrows (reward for defeating the sub-boss), the Giant's Mask (found in a chest), and the Great Fairy's Sword (reward for collecting all the temples fairies). The Boss of this temple is the Giant Masked Insect: Twinmold. After defeating it, Link earns a full heart container and the Twinmold's Remains mask.

It is known to be the second-most topsy-turvy level in Zelda history, second only to the Forest Temple in Ocarina of Time.
