Tycho Curious

The unborn alien baby of Pascal Curious will be born shortly after starting to play the household. Pascal Curious was abducted by aliens before the game started, and he is on his third day of his pregnancy.

In The Sims 2 on PSP, the child was a boy, who was named Tycho. In the story, Tycho was kidnapped by Vidcund Curious to make experiments, just like his dad's friend, Nervous Subject.
