Firestone Lake

Firestone Lake is a location in. It is unlocked after completing Toyku Lighthouse.

Features and Overview
Firestone Lake is a large lake with a giant active volcano, which stands in Koridai's center. The outer area is a desolate wasteland, where the lake's yellowish water steams and boils from the intense heat. Octoroks and Fire Dairas inhabit these shores, the latter of which can only be defeated with Snowballs. Firestones are dropped by the Fire Dairas upon their defeat, from which the lake gets its name. A small Raft on the lake front takes Link further out into the lake, where the region's volcano is. A cave in its side leads inside, where Gwonam can be found in the dark cavern. He informs Link that Zelda has been kidnapped by Ganon during his absence.

Deep in the volcano, Phyrandaii jump at Link in attack, and are also defeated with Snowballs. Grapple Berries are found in one of the crevices. At the bottom of the volcano is an arched exit guarded by a Phyrandaii. After it is defeated, a Fire Diamond is dropped. A Triforce Map exiting the stage then appears. After the stage is completed, Shipwreck Cliff opens as a new stage.
