Rosemarie Jitmakusol is one of the pre-made foreign teenage townies who resides in the tropical Twikkii Island, one of the vacation destination sub-neighborhoods shipped with The Sims 2: Bon Voyage. She can be made playable by befriending and sending her to college[TS2:U], or aging her up with another teen.[TS2:FT] Rosemarie has the same facial structure as Brittany Parker from Pleasantview.
As far as personality, she is very active, and somewhat outgoing and playful. But Rosemarie is very sloppy and somewhat grouchy. When it comes to her skill points, she has 6 points in the charisma skill, and is close to reaching level 7. However Rosemarie doesn't have any other skills. She is mostly interested in Weather, Paranormal, Sports, and Sci-Fi. Like many other Sims from Twikkii Island, Rosemarie has three turn ons instead of two, and two turn offs instead of one.
