The Pegasus Seed is a small seed that grows on the Pegasus Tree and has appeared in a couple of titles to-date. Link can pick them and store them in a Seed Satchel, once he finds it, and they can be used as a substitute Slingshot ammunition. When eaten, they cause Link to dash forward at a much faster speed than usual. When used as a long-range weapon, these seeds will freeze enemies in their tracks.
 The Legend of Zelda: Oracle of Ages
In Oracle of Ages, the Pegasus Tree is located in Rolling Ridge. Its primarily used as a tool to progress, with Link making use of the speed boost to cross the falling floor beneath him in the Great Moblin's Keep. It should be noted that the tree only exists in the past.
