Unlike Brandi Broke, whose child is always a boy, Pascal's baby may be either male or female. Reportedly, there is a higher chance that it will be a girl. There is no chance that twins will be born unless the cheatcode, forcetwins, is used. When it is born, the baby will always have green skin and black hair. Most of the time it will have black eyes, but sometimes they might be dark blue like Pascal's.
The Sims 2 (PSP)
In The Sims 2 for PSP, the child was a boy, who was named Tycho. In the story, Tycho was kidnapped by Pascal Curious to make experiments, just like his father's friend, Nervous Subject.
