Marsha Trimble is one of the pre-made NPC Tinkering Hobby instructors who comes from Hobbies, the secret sub-neighborhood introduced with The Sims 2: FreeTime. The other two tinkering hobby instructors are Ocean Pederson and Erik Futa. She appears in every neighborhood once FreeTime has been installed. Marsha can be made playable by befriending and asking her to move in, or by marrying her. She has long red hair in pigtails, light blue eyes, and tanned skin. Marsha is a Romance Sim with the Libra zodiac sign. As far as personality, she is very outgoing, quite nice, and somewhat playful. But Marsha is very sloppy and lazy.
She is mostly interested in Environment, Weather, Culture, and Crime. Marsha has the same facial structure as Meadow Thayer. Her pre-destined hobby is Nature. Even though her default head-shot depicts him having long hair in pigtails, and a variation of Bella Goth's top with a green necklace, when Marsha is first spawned in-game, she will have medium-length hair in a ponytail with a dark blue hat. She will also wear a dark blue suit. However Marsha will still retain the hairstyle in her default thumbnail, for most outfits besides everyday.
