As each new Expansion Pack comes with a new creature, The Sims 2: Seasons comes with Plant Sims. Any adult Sim can become a Plant Sim and Plant Sims are playable characters.
Appearance and Behavior
Plant Sims have green skin with vine-like tattoos, special leaf or flower made hair and yellow eyes. Plant Sims only age within three life stages: Toddler, Adult and Elder; thus, they lack the Baby, Child, and Teen stages, nor Young Adult. Besides aging differences, they have three needs: Sunlight (satisfied by going outside or using a sun lamp), Water (satisfied by taking showers or baths, being outside in rain, or by swimming) and Love (equivalent to the Social need). Plant Sims also gain a prank interaction, the ability to spawn offspring and release spores of happiness, which boost nearby Sims' needs. Spawned offspring have a gold gardening badge and the same skills and personality as their parent. They also have a 50 percent chance of inheriting the other, non-gardening talent badges from their parent. Plant Sims cannot enter the Very Hot temperature level and will never get heatstroke. If their overall mood drops below zero or their water level is very low, Plant Sims will appear wilted.
How to Become
In order to become a Plant Sim, a Sim must spray their orchard trees or plants in excess. The Plant Sim condition can be "cured" if a Sim buys the Plantophic-C from the Garden Club or the Gypsy, a NPC available in The Sims 2: Nightlife expansion pack.
Sporing Plant Sim babies
Another possible way of becoming a Plant Sim is for another Plant Sim to spore a baby Plant Sim. This is done by a self-interaction of the parent Plant Sim and can be done whenever. It only takes a few Sim minutes for the Plant Sim to be spored and will always result in a child being born (unlike Try for Baby) unless there isn't enough room in the household. This way, multiple Plant Sim spores can be born in one Sim day.
Pros: Plant Sims have easy needs, a Gold Garden badge, and reproduce quickly.
Cons: Plant Sims have a short lifespan and cannot go to college.
Plant Sims can also reproduce by WooHoo (both getting pregnant and impregnating). The resulting child will not have any Plant Sim traits, and will carry the genes for whatever hair and eye color the parent Plant Sim had before their transformation.
A Plant Sim is included in the new Seasons neighborhood, Riverblossom Hills. She lives in the Greenman household with her (non-Plant Sim) husband and (Plant Sim) spawned child.
