Life leading up to The Sims 2
Oddly Prudence's tombstone can not be found in the Goth Family graveyard or anywhere else for that matter so it is presumed that her tombstone was destroyed by someone, or that the creators of the game made a grave mistake just like they did in The Sims 3 for Frida Goth. She has the same hairstyle as she did in The Sims 3, and wears a blue cardigan with cream colored pants.
