When it comes to Pao's skill points, he has maximized the creativity skill, and is well on the way towards maximizing the cooking and logic skills. He is mostly interested in Weather and Travel. Pao has the same facial structure as Ian Tan. He can easily be cloned in Create a Sim with debugging mode on. Pao's turn ons/offs are randomized at the start of the game. It is only referenced in the game files that he has no turn ons/offs. Often going unnoticed, Pao has 28 personality points instead of the usual 25.
Do NOT attempt to add Pao to a household, make him selectable, turn him into a supernatural creature, or tamper with him in any way or form. Doing so will corrupt the neighborhood he is in.
