Firecorn

The Firecorn is an explosive material featured in the A Link to the Past comic. It is only found in the Palace of Darkness.

History
When Zora tells Link that one of the maidens is imprisoned in the Palace of Darkness, he warns the young hero of the dangerous firecorn that are kept in there. Despite his warnings, Link goes to the palace anyway and eventually finds the storeroom where Ganon's minions keep the firecorn. Link is eventually caught by a Rocklops and warns him of what could happen if he set off the firecorns in the palace, but the young hero disregards his warning and takes a Hinox's bomb belt that was wrapped around it. Giving Epheremelda ones of the bombs from the Hinox's belt, the bomb eventually denotes the firecorn stockpile and destroys the entire   palace, freeing the Maiden in the process.
