Happy Mask Shop
The Happy Mask Shop is found in Hyrule Market in Hyrule Castle Town in Ocarina of Time, to the right of the entrance to Hyrule Castle.
It is the base for the game's Mask Trading Sidequest and is run by the Happy Mask Salesman.
The shop will open after you give Zelda's Letter to the guard in Kakariko Village.
You can cheat at the mask side quests by leaving, entering and paying if you have enough rupees.
