The Legend of Zelda: Ocarina of Time/The Happy Mask Shop

The Happy Mask Shop is located in Hyrule Castle Town Market, to the right of the path to the castle. The shop itself does not sell masks; rather, it lends them to aspiring individuals for sale. If a mask is sold, you pay back the price of the mask but get to keep any extra rupees, and are granted access to a newer mask model to sell. You can borrow masks you have already sold again; however, you can sell each model of mask only once. Masks are event items, and you can carry only one mask at a time. To see if someone is interested in purchasing a mask, talk to them while wearing it.

The Masks
Wearing masks while speaking to people can elicit different responses.

Keaton Mask - This popular mask is modeled after the wily keaton fox.

Skull Mask - This monstrous mask will make you look like a Skullkid.

Spooky Mask - This scary mask is similar to a Re-Dead's face.

Bunny Hood - Some people believe that this set of bunny ears will make you run faster and jump higher.

Goron Mask - A mask that looks like a Goron.

Zora Mask - A mask that looks like a Zora.

Gerudo Mask - A mask that looks like a Gerudo.

Mask of Truth - This mask can be used to obtain hints from Gossip Stones, and read people's inner thoughts.

The trading sequence
Keaton Mask: This is the first mask you can borrow from the Happy Mask Shop. Take it to Kakariko Village and wear it while talking to the guard protecting the gate to Death Mountain. He will buy the ten rupee mask for fifteen rupees, and you will be able to borrow the Skull Mask.

Skull Mask: After obtaining this mask, enter the Lost Woods from Kokiri Forest and go left. Put on the mask, stand on the stump, and talk to the Skull Kid. He will only give you 10 rupees for the 20 rupee mask, but you will now be able to borrow the Spooky Mask.

Spooky Mask: During the day, go to the Kakariko Graveyard and show the kid there the Spooky Mask. He will buy it at full price for thirty rupees.

Bunny Hood: After borrowing the Bunny Hood, enter Hyrule Field and play the Sun's Song to make it nighttime. If facing Lon Lon Ranch, head right to stream surrounded by bushes and trees. A man should be resting at one of the far trees, so talk to him while wearing the Bunny Hood. He will give you all his money for the mask, granting you access to the Mask of Truth, Gerudo Mask, Goron Mask, and Zora Mask.
