Ninja
The ninja is an NPC from The Sims 2: Bon Voyage. He only visits Takemizu Village or custom far-east vacation destination lots. Sims can learn teleporting from him.
Learning to Teleport
In Takemizu Village or custom far-east vacation destinations, sometimes a ninja NPC will randomly teleport into the lot. He'll hop around for a little while, teleporting, and if a Sim clicks on him the only option is "Learn to Teleport." If the player choses this, the ninja will ask a question with two answers. This question works like a chance card, where it doesn't really matter which option is chosen, because each has a correct and incorrect possibility. If correct, the Sim will gain the ability to teleport.
Teleporting
After correctly answering the ninja's question, a new option will appear when clicking on the ground. Along with "Go here" and "Run here" is the option "Teleport here". This is significantly faster than walking. The Sim will backflip into a puff of smoke and reappear over the destination. They will have this ability forever.
Appearing near other Sims, scares them.
