Mushroom

Mushrooms are a recurring item in.

A Link to the Past
In, the Magic Mushroom can be found within the Lost Woods. Link can offer it to the Witch in exchange for the Magic Powder.

Link's Awakening
In, the Sleepy Toadstool is found in the Mysterious Woods. It can be given to the Witch to be made into Magic Powder. The Sleepy Toadstool can cause unusual effects when eaten. Tarin, who has a fondness for mushrooms, had eaten one while at the Mysterious Woods and was transformed into a raccoon. Link uses the Magic Powder to turn him back to normal.

Ocarina of Time
In, the Odd Mushroom is part of the Trading Sequence. The Young Punk Guy gives the mushroom to Link in exchange for Cojiro. The mushroom is then to be delivered to the Old Hag in Kakariko Village to be made into the Odd Potion. The Odd Mushroom goes bad after three minutes (or instantly after warping).

Majora's Mask
In, a Magic Mushroom's scent can be detected with the Mask of Scents and stored in an empty Bottle. They can be found behind a Deku Baba in the Southern Swamp; in the Woods of Mystery; and inside the Stock Pot Inn, on Gorman's bed (cannot be collected while Gorman is sleeping there) and in the restroom (cannot be collected while ??? is there). They reappear when Link leaves the area.

The Magic Mushrooms can be sold to the Magic Hags' Potion Shop for 40 Rupees each; at least one must be delivered during that cycle before Blue Potions can be purchased there. They can also be sold to the Curiosity Shop for 5 Rupees each.

Oracle of Seasons
In, a Mushroom appears as a Trading Sequence item. Using the Megaphone, Link can wake up Talon in a cave atop Mt. Cucco. In exchange for waking him, Talon offers Link a Mushroom, which can in turn be given to Syrup in Sunken City in exchange for the Wooden Bird.

Rock Mushrooms, also known as Petri Fungus, also appear as obstacles in Holodrum. They are a rock-solid fungus that can only be picked with the Power Bracelet during the autumn season.

The Minish Cap
In, the Wake-Up Mushroom is required for Link to obtain the Pegasus Boots. It is bought from Syrup the Witch at the price of 60 Rupees. It is then given to Rem, the owner of Rem's Shoe Store, waking him up. In return, Link will receive the Pegasus Boots.

Elastic mushrooms can also be found in certain areas while Link is shrunk to Minish size. The Gust Jar can be used to suck and pull back the mushroom caps, which will then throw Link once released.

Skyward Sword
In SS undefined, mushrooms can be found in the Faron Woods, Deep Woods, Skyview Temple, and on certain islands in The Sky. Link can slash them with his Sword to produce Mushroom Spores, which can be stored in Bottles and used to heal Loftwings. Glittering mushrooms can also be found, which produce Glittering Spores than can also be stored in Bottles. They produce different kind of effects when used on items and enemies.

Trivia

 * In Link's Awakening, the Mushroom is one of many references. When Tarin (who bears resemblance to, and also shares his love of mushrooms) eats one, he turns into a raccoon, which may be a reference to Mario's  or  transformations.
