Seed Shooter

The is an OoA: in.

Location and Uses
It is found in the third dungeon, the Moonlit Grotto. The Seed Shooter's function is similar to the Slingshot in and various other Zelda games, except that the Mystical Seeds shot from it can go in eight directions, and they will bounce off walls and some other objects. A fired seed will disperse on its third bounce, or after hitting a certain object, such as a torch, or an enemy. It is also capable of firing seeds diagonally, making the seeds bounce around corners. This allows Link to hit various targets, which is necessary to solve various puzzles.

(Himekawa)
The Seed Shooter is called the Pea Shooter in the manga, since it is translated from Japanese. It is held by a young boy hiding from Queen Ambi's soldiers in a cave. He tells Roperi not to worry about soldiers because he will beat them with it. Roperi says the Shooter will not be enough. When Roperi's Mystery Tree sapling produces a Mystery Seed, Link takes the Shooter with him to the Black Tower, where Ralph is preparing to kill his ancestor Queen Ambi to destroy Veran. Link says he will not let Ralph throw away his existence and shoots the seed, forcing Veran from Queen Ambi's body.
