Ninja is one of the pre-made ninjas from The Sims 2: Bon Voyage. He only visits Takemizu Village or custom far-east vacation destination lots. Sims can learn teleportation from him.
Like all ninjas, he can't be interacted with. As a result, he can't be made playable without cheats. Ninja has the same facial structure as David McClellan.
He can easily be cloned in Create a Sim with debugging mode on. Ninja has short black hair in a buzz cut. Even though he has black hair, his natural hair colour is actually red.
Do NOT attempt to add Ninja to a household, make him selectable, or tamper with him in any way or form. Doing so will corrupt the neighbourhood he is in.
