The Deku Mask is a mask from The Legend of Zelda: Majora's Mask. This mask, shaped like the face of a Deku Scrub, allows Link to transform into one; a shape informally known as Deku Link. It is the very first mask obtained in the game, and the first of the game's transformation masks. While wearing the mask, Link gains new abilities that are not available in his standard Hylian form.
