All-Night Mask

The All-Night Mask allows the wearer to never fall asleep. In fact, it is impossible to fall asleep while you are wearing it.

While you will need an entire three day cycle to obtain the mask, it has only one use in the game. If you wear the mask while listening to the stories of Anju's Grandmother then you will not fall asleep. At the end of each story, Anju's Grandmother will ask you a simple question and if you give the appropriate answer then you will receive a Piece of Heart.

Obtaining The Mask
Day 1: Complete The Oceanside Skulltula House
 * The Oceanside Skulltula House is located at the Great Bay. If you visit and complete it by collecting thirty Gold Skulltula tokens before the end of the first day, then a man near the exit will reward you with the Giant's Wallet.

Day 1: Save the Old Lady from Bomb Shop
 * At 12:15 on the night of the first day, Sakon will try to rob the Old Lady from Bomb Shop in North Clock Town. Stop the thief by attacking him with your sword. If this is the first time you have saved the old lady then you will be rewarded with the Blast Mask. If you have saved her before, then you will simply get a thanks, but it is a necessary step in obtaining the mask.

Day 3: Purchase The Mask
 * The last step is simple, but you will need five hundred rupees. Show up at the Curiosity Shop on the night of the third day. Since Sakon was unable to steal the Blast Mask from the old lady, he will have sold the All-Night Mask to the Curiosity Shop, and it will be available for 500 rupees.
