Black Eggs are hollowed-out bird eggs filled with blinding substances. They were the Mid-Range Weapon of the Ninja. Filled with crushed glass or pepper. Black Eggs are hollowed out poultry eggs that were filled with either glass powder or pepper juice and painted black. Black Eggs are used to blind enemies by throwing them or their contents at the target's eyes. Glass-filled eggs would be crushed prior to throwing for maximum dispersion, which would effortlessly hit the eyes behind the enemy's mask. Black Eggs are not lethal weapons, but the amount of blinding pain the target suffers leaves them wide open for attack. The weapon actually started a myth that ninjas could disappear in a cloud of dust.
