Garo's Mask
From Zelda Wiki, the Zelda encyclopedia
The Garo's Mask, given to Link by the Gorman Brothers, resembles the head of a Garo Ninja. Wearing it allows entry into Ikana Canyon, as well as the ability to encounter and battle against Garo Ninjas. If defeated, the Garo Ninja will reward Link with a tip that may help him on his quest.
If ReDead see the mask, they will dance, allowing Link to walk past them without any trouble.
