Mystery Seed
From Zelda Wiki, the Zelda encyclopedia
Mystery Seeds are Mystical Seeds with a very strange effect. When placed on Owl Statues, they bring the statues to life! They also cause weird things to happen when placed on enemies and other things. Try putting them on just about anything you meet. Mystery seeds are to defeat posessed Nayru and posessed Ambi.
These seeds grow on Mystery Trees. In Holodrum, these trees produce seeds during all the seasons.
