Skull Mask

The Skull Mask is a mask from The Legend of Zelda: Ocarina of Time. It may be obtained at the Happy Mask Shop by paying for the Keaton Mask, and costs 20 Rupees. The Skull Mask is made to resemble the skull of an unknown creature, and has no relation to Stalfos or Skull Kids other than that. However, the Skull Kid from Majora's Mask wears the Skull Mask before obtaining the Majora's Mask. This is the Skull Kid who wants the Skull Mask in Ocarina of Time.

The Skull Mask has a special power: Keese are unable to view Link, similar to how the Stone Mask works in Majora's Mask.
