Rather than an update to the current ones I would prefer a fully fleshed out PlantSim lifestate to come in a pack. That way those who like them as they currently are can keep that, but those who want a better permanent PlantSim can have it. I'd like a PlantSim lifestate that I can edit in CAS, and that has unique PlantSim abilities and interactions and is a permanent lifestate unless I choose to change them to a regular Sim. I like the way they did it with mermaids and the mermadic kelp. It could be done with some kind of seed.
