Odd Potion

The Odd Potion, also known as the Odd Poultice in Ocarina of Time 3D, is an item in the Adult Link Ocarina of Time Trading Sequence.

Location and Uses
To make the Odd Potion, Link must bring the Odd Mushroom he received from Grog in the Lost Woods to Granny's Potion Shop in Kakariko Village before it spoils. Granny will then give Link the Odd Potion, to be brought to Grog. However, when Link returns to where he found Grog, Fado will be there in his stead. She will explain that Grog has fell under the curse of the Lost Woods, turning him into a Stalfos, and that only the saw that he had remains. This saw is in fact the Poacher's Saw, which Fado will give to Link in exchange for the Odd Potion.

It is implied that the Odd Potion is a cure for the curse of the Lost Woods. This would explain Grog anxiousness when he gives Link the Odd Mushroom. It also explains why Granny says that the Odd Potion will not work on monsters, implying that the Odd Potion will not work if Grog has already transformed into a Stalfos.
