During an interview with EA, Sims 3 Cri was able to confirm that Mermaids will be the new lifestate/creature for Island Paradise! Mermaid lovers rejoice! 😀
We do not know if there will be a new neighborhood or you can buy these houses, the video showed only the houseboats in general. However, we can confirm that there will be mermaids! We have not seen in action but all the EA have confirmed that there will be!
