Romani's Mask
Romani's Mask is one of 24 collectible masks in Majora's Mask. It is worn like a cap and means that Link is a full member at the Milk Bar establishment.
Obtaining the Romani's Mask
After you help Cremia keep the Gorman Brothers at bay during their travels from the ranch to Clock Town, she pays Link with the Romani's Mask once the two are outside of Clock Town. Link has to simply fire arrows at the brothers as they trail behind the carriage on horseback. The mask can only be obtained after Link has helped Romani defend the ranch against Them and is given a bottle full of Romani Milk as his reward.
Uses
The Romani's Mask is used to gain access to the ever-exclusive Milk Bar in East Clock Town. Link is originally not allowed to enter the bar, and it symbolizes that he indeed a member. The mask is useful in helping obtain the Circus Leader's Mask, bottles of expensive Chateau Romani and one of six bottles to be found in the game.
