Servos... Need Making Business, and Nightlife
Okay I learned this by pure accident, if you buy a robot desk thing and have your Sim get a golden badge on it (It takes a while but it's worth it).
Then have your sim make Servo once you choose it's name and gender. It can do just about anything a sim can except have babies.
The coolest part is if you have your Servo meet a vampire you can turn the servo INTO a VAMPIRE.
It looks a bit goofy with big walrus fangs and a red eye.
But I'm not sure what happens to it during the day.
