Subrosian Volcanoes

Subrosian Volcanoes are the volcanoes located beneath the Temple of Seasons in Holodrum. They play a role in reaching the eighth dungeon in Oracle of Seasons. You will find a Subrosian throwing random items in a lava pit inside a small cave in Subrosia. To activate it, throw a bomb in the pit and all the volcanoes will erupt, filling the Temple of Seasons in the overworld with lava and so making it possible for Link to reach it.
