How to make an existing sim a mermaid?
I made a sim to be my heir's partner but I made a regular sim. She's all done but I want her to be a mermaid. I am willing to cheat as I'll play her from YA and up. Can it be done in CAS only? Also...

I'm not sure if you could make a sim a mermaid without playing them, but you could always make them a mermaid then just mark them as unplayed in the household management bin, and they'll still act like every other NPC.
