Eyeglass Pond

In Oracle of Seasons, Eyeglass Lake is a lake found north of Horon Village in Holodrum. This area's default season is Winter, freezing the lake over. The fifth dungeon, Unicorn's Cave, can be found here.

Eyeglass Lake is so named because of the two islands in the lake, giving it the appearance of eyeglasses. One island has a bridge connecting it to the mainland, and a treasure chest containing a Gasha Seed. The other island has a shark fish patrolling it for some reason; there are six Rock Mushrooms and a portal to the Autumn segment of Subrosia on it.

In a linked game one of the jewels is there in a cave,to get it,you need to change the season into Summer.
