Magic Powder

Magic Powder is a recurring item in the Legend of Zelda series.

The Legend of Zelda: A Link to the Past
In A Link to the Past, Magic Powder is formed out of a mushroom, like those found in the Lost Woods. A Witch can make the powder for Link if he brings her a mushroom.

The Magic Powder is usually used in A Link to the Past to transform enemies; Buzzblobs can be turned into Cukemen, Anti-Fairies into Fairies, and certain enemies into harmless piles of slime.

Sprinkling Magic Powder on the strange statue near the Blacksmiths' house awakens a bat-like creature who then "curses" Link, cutting the Magic he uses by half.

The Legend of Zelda: Link's Awakening
In Link's Awakening, Magic Powder can either be created by a witch after Link gives her the Sleepy Toadstool, or it can be won in the Trendy Game.

It is used mostly in Link's Awakening to construct fires and kill certain enemies, though it can also be used to wake Tarin from an odd slumber.
