All-Night Mask

In Majora's Mask, the All-Night Mask is a mask with the power to prevent its wearer from falling asleep.

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

Obtaining The Mask
Link can purchase this mask from the Curiosity Shop on the night of the final day for 500 Rupees if he protects the Old Lady from Sakon's attack on the night of the first day. If he allows Sakon to steal her bag, the mask will not appear.

The Wind Waker
The All-Night Mask appears alongside several other masks behind the counter of the Nintendo Gallery. It can be seen hanging on the wall behind Carlov.
