Basically, there is a chance that once you defeat Skeletron a ninja invasion can happen rarely. When the event occurs there are two types of ninjas;katana ninjas, and shuriken ninjas. The katana ninjas can rarely drop a katana (About a 2% chance). The shuriken ninjas always drop 1-5 shurikens on death. Both ninjas can rarely drop a piece of the ninja armor. After the invasion has been completed a ninja NPC will spawn if there is a vacant house, they sell a katana, (16 gold) shurikens (25 silver), and master ninja gear post-golem (4 platinum). The summon item for the ninja invasion would be crafted with 5 shurikens, and 5 iron/lead bars. It would be called the "Ninja Emblem". (Concept art for Ninja emblem attached below) (The ninjas and ninja NPC would look like the ninja trapped in King Slime)
