While I was looking through the mods section of modthesims.info I stumbled across a mod titled “Hidden Traits Unlocked”.  I decided to take a look at it and download it into my game.  As it turned out, there are a dozen traits that are built in to the game but are not available in CAS.  This mod unlocks those traits and makes them available in CAS.  The traits and how to get them are as follows:

Note: every trait is inherited by the resulting child

Physical:

  1. Pyromaniac – Having a child with a firefighter
  2. Immune to Fire – Having a child with a firefighter (my guess, and this is just a guess to how to get one over the other is the gender of the firefighter)
  3. Makes No Messes – Having a child with a maid
  4. Mummy – Having a child with a mummy

Mental:

  1. Burglar – Having a child with a burglar
  2. Can Apprehend Burglar – Having a child with a cop
  3. Can Salute – Having a child with a Military Sim
  4. Pizza Appreciator – Having a child with a Pizza Delivery Sim
  5. Rocker – Having a child with a Rockstar
  6. Asian Culture – Having a child with a sim from the China destination in WA
  7. Egyptian Culture – Having a child with a sim from the Egypt destination in WA
  8. French Culture – Having a child with a sim from the France destination in WA
