Harlequin Bazaar

Harlequin Bazaar is the second dungeon in Link: The Faces of Evil. It is only available once Link completes Goronu.

Overview
Harlequin Bazaar is a dungeon run by Harlequin, where he transforms Koridians into Goriyas after they run out of "rubies". It appears to be a functioning bazaar, with various shops, a dunk tank and even an auction. At the end of the dungeon, Link faces off against Harlequin. Once he is defeated, Link obtains a key that opens a door in the boss room. Inside is the Astronomer, who will take the Ice Crystal and add it to the Lantern to create the Magic Lantern. Once the area is completed, it opens up the Militron as a new area.
