Sims 2, The Easter Egg - Bella Goth in Strangetown

I'm pretty sure that this occurs only by chance, but if you play The Sims 2 in Strangetown, you may end up meeting Bella Goth. I almost fell out of my chair when my sim was making breakfast and Bella just strolled past the house. She was wearing the red dress and everything!!! I wanted to make sure it really was her first, so I got my sim to be friends with her, and sure enough when they first met, on the relationship meter thingy it said she was Bella Goth! I got my sim to fall in love with her and she eventually moved in. She didn't bring that much money, and her job was a bank robber. However, I moved her back into Pleasantview to see what would happen if she met Mortimer and unfortunately, they treated eachother like a normal sims... It was pretty cool though.
