Giant Ghini is an enemy that has appeared in two different The Legend of Zelda games.
There is only one Giant Ghini on all of Koholint Island in Link's Awakening. It is located in the upper right part of the Cemetery. By touching the lower right gravestone, this huge ghost will come out and attack Link. They take the same number of hits as a small Ghini. They will just fly around the screen, chasing after Link sometimes.
Oracle of Ages
In Oracle of Ages, the Giant Ghini appears as a mini-boss within the first dungeon, Spirit's Grave. This version is accompanied by three smaller ghosts. Link can get rid of these smaller ghosts with a simple sword slash and can then attack the Giant Ghini directly. Link must act fast though, as the pesky smaller ghosts respawn quite quickly.
Four Swords Adventures
Giant Ghinis appear only on the stage The Swamp, a part of the level Near the Fields. Link first sees them crowding around Dampé's house. They cannot be killed with just the sword in Four Swords Adventures; instead, the four Links must each stand on a nearby switch, and when all four are pressed, the four torches surrounding the house become lit. Any Giant Ghinis that touch the light will die instantly.
Giant Ghinis also appear before the boss battle with Jalhalla. When the Links enter the area, they see four of them standing by unlit torches. Again, they have to step on switches to light up the area and defeat the enemies, causing Jalhalla to appear.
