In both PC and Console versions of The Sims 3, you can add an alien baby to your family.
This has to be done with a male character. Have the male sim look through the telescope, and there is a chance that he will be abducted and implanted with an alien baby.
The baby doesn’t act any differently, it acts exactly as any other baby would, it’s just greenish blue and has huge eyes.
