Heidi Kalson is one of the pre-made NPC gardeners who resides in Four Corners, one of the neighborhoods shipped with The Sims Life Stories. The other two gardeners are Maura Wilson and Derek Gibson. She can be made playable by befriending and asking her to move in, or by marrying her. Heidi has long blonde hair in pigtails, green eyes and dark skin. She is a Romance Sim with the Taurus zodiac sign. As far as personality, Heidi is very active and somewhat outgoing. But she is very sloppy, quite serious, and somewhat grouchy.
When it comes to Heidi's skills, she has maximized the charisma skill, and is close to maximizing the cleaning skill. She is mostly interested in Politics, Crime, and Sports. Heidi has the same facial structure as Noelle Sartor. Her turn ons/offs are randomized at the start of the game. It is only referenced in the game files that she has no turn ons/offs. Often going unnoticed, Heidi has 22 personality points instead of the usual 25.
