Happy Mask Side Quest
The Happy Mask Side Quest is a trading sequence in Ocarina of Time. It is not required, but completing it is the only way to acquire the Mask of Truth, which can be used to read the Gossip Stones scattered across Hyrule. This side quest consists of borrowing masks from the Happy Mask Shop in Castle Town and selling them to characters in other places. There is only one buyer in Hyrule for each mask.

The Keaton Mask is the first mask available in the shop. It needs to be taken to the guard standing by the entrance to Death Mountain. Earlier in the game, he actually says that he wants a mask for his son, and he will buy it for full price.
Skull Mask

The Skull Mask is the second mask available in the shop. It needs to be taken to the Skull Kid in the Lost Woods who stands on a stump playing his flute. He will give Link a Piece of Heart if he plays Saria's Song, and if he sees the mask he will buy it. Unfortunately, he only pays 10 rupees for the 20 rupee mask, so Link has to pay the rest with his own money.
Spooky Mask

The Spooky Mask is the third mask available in the shop. It needs to be taken to the Boy in the Graveyard (in the Kakariko Graveyard), where he will comment on how spooky it is and instantly buy for the full 30 rupee price.
Bunny Hood

The Bunny Hood is the final mask that Link must sell in order to complete this side quest. It needs to be taken to the Running Man, who can only be found after Link completes Inside Jabu-Jabu's Belly. He will be found running around Lon Lon Ranch. He occasionally stops to take a rest, and that is the only time Link can talk to him. He will be so excited about the mask, and will completely fill up Links wallet, no matter which wallet he has. After putting on the mask, the Running Man somehow gained the power to run super fast, and he will dash away very quickly.
Now Link can go back to the Happy Mask Shop and the Mask of Truth will be available to borrow, along with the Gerudo Mask, the Goron Mask, and the Zora Mask.
