Mermaids confirmed for Island Living!!!

Playable mermaids should 100% have the OPTION To spend their whole lives under water should they so choose. Meaning all their needs need to be bale to be taken care of underwater. This is possible in sims 3 for the most part except energy.

Also, on land NPC mermaids should be very rare, and only in beach worlds. I don't want to see mermaids wandering the desert. Even in the water they should be rare.
