Mystery Milk

is an item in.

Location and Uses
From 6 am to 12 pm on the Second Day, if Link wears the Troupe Leader's Mask and talks to Gorman while he is sleeping in the Stock Pot Inn's bunk room, Gorman requests Link bring him Mystery Milk from his brothers at their ranch on Milk Road. However, he will not request any milk if Link cheered him up by playing the "Ballad of the Wind Fish" in the Milk Bar the night before.

After receiving the request from Gorman, if Link talks to the Gorman Brothers from 12 pm to 6 pm while wearing the Troupe Leader's Mask, they will give him the Mystery Milk.

After 2 minutes (actual time), the Mystery Milk spoils and turns into Moldy Milk. This counter is unaffected by the "Song of Double Time" and the "Inverted Song of Time."

If Link successfully delivers the unspoiled milk to Gorman from 12 pm to 6 pm, he will let him keep the empty Bottle. Afterwards, doing the sidequest on another cycle will yield a Fishing Hole Pass. After 6 pm, he will not acknowledge that Link has the milk.

If Link plays the "Song of Soaring" or tries to put on the Goron Mask while he has the Mystery Milk, Tatl does not let him warp or put the mask on, saying that flying or rolling as a Goron will spill the milk. If Link tries to drink the Mystery Milk, Tatl will not let him, telling Link that she would end their friendship if he did.

If Link plays the "Song of Soaring" or tries to put on the Goron Mask while he has the Moldy Milk, or tries to use the Moldy Milk, Tatl will interrupt him (preventing Link from warping, putting the mask on, or doing anything with the milk), begging him to dispose of the foul milk. If Link talks to the Gorman Brothers while he has the Moldy Milk, they will exclaim in disgust at the awful smell.

Unlike all other bottled items, if Link returns to the start of the First Day with the "Song of Time," Link will also lose the bottle containing the Mystery Milk or Moldy Milk.

Trivia

 * Despite smelling worse than a Goron's armpit, Link does not react to the Moldy Milk while wearing the Mask of Scents.
