- "That is the Mask of Scents, isn't it? You've done well to get that mask. Looking at its condition, I can tell that its previous owner was neat and tidy."

The Mask of Scents is one of the twenty-four masks that Link can collect in The Legend of Zelda: Majora's Mask. It enhances the wearer's sense of smell. Link is given this mask by the Deku Butler, as a belated reward for rescuing the Deku Princess and restoring peace to the Southern Swamp, after he manages to keep up with him in a race through the Deku Shrine.
The Mask of Scents allows Link to track the odor of Magic Mushrooms with ease; these are represented by purple fumes that are seen only when the mask is worn. These mushrooms can be stored in bottles and brought to Kotake at the Magic Hags' Potion Shop for her to make Blue Potion, using the Magic Mushroom as an ingredient. Magic Mushrooms can be found in various places, including the Woods of Mystery and many hidden grottoes, but the most interesting is likely the Stock Pot Inn; if Link visits the bunk room on the second floor where the Gorman Troupe is staying, he can use the Mask of Scents to find a Magic Mushroom hidden within a pair of boxers on one of the beds.
The shape of the Mask of Scents resembles a hog, a pig, or possibly even a Moblin; this is likely because pigs are known for their acute sense of smell. In addition, pigs are known for their ability to sniff out Truffles, a rare type of mushroom. The Mask of Scents has the same color as Link's skin; when worn, Link looks like a humanoid pig, rather than a human wearing a pig mask. In addition, when worn, the mask replaces all of Link's shouts and grunts with pig noises and his idle stance with a hunched-over, "sniffing" animation.
Interestingly, the Mask of Scents is virtually identical to the "Piggy Nose" item from EarthBound, which is also used to find mushrooms, specifically Magic Truffles. The mask may also be a reference to Pigma Dengar from the Star Fox series; both are pigs and have black around the eyes, though Pigma lacks the tusks that the Mask of Scents has.
