Deku Seed

Slingshot Pellets are items, usually seeds, that are used as ammunition in a slingshot. The ammunition is different depending on the slingshot used.

Deku Seeds
Deku Seeds are found in Ocarina of Time. They are common items, especially inside the Great Deku Tree. These seeds are used as ammunition for the Fairy Slingshot. The Deku Seeds can only be used as a Child due to the Fairy Slingshot not having any use as an adult. They are held in the Bullet Bag, which can be upgraded to hold 40 or 50 seeds.

On another note, the enemy Skull Kid shoots Deku Seeds from his flute. These aren't particularly strong, but they are shot fast.

Mystical Seeds


Mystical Seeds are a type of ammunition for the Slingshot or Seed Shooter introduced in Oracle of Ages and Oracle of Seasons. There are five types: Ember, Scent, Pegasus, Gale, and Mystery. These seeds are held in the Seed Satchel.

Pellets
Pellets are a type of Slingshot ammunition introduced in Twilight Princess. Link receives 50 pellets when he first buys the slingshot from Sera in Ordon Village, but must use pumpkin seeds or deku seeds as replacements once they are used up. The former appears by smashing pumpkins, while the latter is obtained by killing Deku Babas and opening their pods. There is no bag or container for pellets, but a maximum of 50 pellets can be held.
