Jack Trimble is one of the pre-made townies who resides in Bitville, one of the neighborhoods shipped with The Sims Life Stories. He can be made playable by befriending and asking him to move in, or by marrying him. Jack is employed in the Military career as a Flight Officer at the start of the game. He has the same facial structure as Jihoon Hsu.
As far as personality, Jack is very active and quite playful. But he is very sloppy, quite shy, and somewhat grouchy. When it comes to his skills, Jack is halfway towards maximizing the body and creativity skills, but he doesn't have a particularly high level in any of the other skills. He is mostly interested in Food, Politics, and Fashion.
