Ok, so I’ve only played sims 4 and mobile. Neither of which have mermaids... which make me wonder... did all the past sims games have mermaids? If so, how would you play them since they swim and don’t...
Someone is writing a story, in the story is a mermaid as one of the main characters in Sims 3. But basically, a TS3 mermaid would have legs while on land, but those legs would turn into a fishtail when they were well into the water (not including baths or showers).
