Hebra's Hill
ERROR: No image specified. Please specify an image. Hebra's Hill is a location in Death Mountain Foothills, part of the third stage in Four Swords Adventures. At first it is overwhelmed by Hinox, and Link must go right to reach a cave with a mage who gives him a Quake Medallion. Once Link throws it, all of the enemies will turn into ChuChus. Once all dead, the spike barrier drops and Link may continue up a staircase.
Halfway up the stairs is a rift that brings Link to some sort of pocket dimension where each screen holds the same thing: 12 brown, unliftable rocks, and a fleet of stairs. Link has to walk up the stairs several times before reaching the other side of the stairs. This plays out similarly to the Lost Hills in the original The Legend of Zelda.
