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.

Onamotology
Tycho Curious' name, like many of the curious family names, seems to come from science. He is likely named for the Danish atronomer and nobleman Tycho Brahe, who ran the decadant and lavish Uraniborg on the island of Hven in the late 1500's, worked with Johannes Kepler, and famously lost a section of his nose in a swordfighting duel.
