The Subterranean Lake, also known as the Underground Lake, is a location in Final Fantasy III. The party enters it by jumping into the lake in Dwarven Hollows while in the Toad status. This is where Gutsco has taken the stolen Horn of Ice.
The Warriors of the Light chase Gutsco, who stole one of the Horns of Ice from the Dwarven Hollows, in order to retrieve the Dwarven relic. They easily find Gutsco at his hideout, along with his stolen stash and defeat him, retrieving the Horn of Ice.
