Ammunition, or ammo for short, refers to any item which can be used as a projectile in a Bamboo Blowgun or a Bow, etc. Two different forms of ammunition in the game include Arrows and Throwable Seeds. To use ammunition, the player must place it in the ammunition slot in the player's inventory, which is the slot which appears to have an arrow in it. To fire a weapon, the player must tap anywhere on the screen with the Weapon in hand.
Throwable Seeds can be acquired in two ways: They are dropped (in batches of 2 or 3) when destroying Sunflowers and can also be obtained (in batches of 6) by placing a Watermelon in the crafting grid (No Addon is needed for this recipe). Despite its name, Throwable Seeds can't actually be thrown, but instead are used as ammunition for the Bamboo Blowgun.
Arrows can either be crafted in a Tinkerer's Tools, or found in Chests. These items can only be used in Bows. They can be crafted out of wood and each of the metals (except Bronze), with each of the arrows varying in damage points.
Note: The Love Arrow is only dropped from Zombie Cupids and Valentine's Chests.
