Mermaids in The Sims 3 Island Paradise Expansion Pack

Mermaids are the new Occult Life State in The Sims 3 Island Paradise Expansion Pack. This Guide to Mermaids I will teach you how to turn your Sim into a Mermaid, and the perks to playing a Mermaid. I'll provide tips to befriending a Mermaid quickly to access Mermadic Kelp and transform your Sim, while also having the Mermaid lead you to the Uncharted Private Island, Mermaid's Secret.

Mermaid Features: Swimming and Diving
As should be expected, Mermaids grow legs when walking on land and fish tails when swimming in the water. Mermaids are immune to Drowning death thanks to their gills and Steel Lungs would be a useless Lifetime Reward for them. Naturally, they Swim much faster than normal Sims. Because of their expertise in the water, Mermaids automatically get level 10 in the Diving skill upon aging up to teen but still need to complete the Skill Challenges. As Mermaids are naturally attuned to life in the water, they do not suffer Decompression when they are done with a Dive. The 'Scuba Dive' option on Dive Spots changes to 'Dive Underwater' instead.

In order to stay a Mermaid, a Sim needs to Swim at least once every 48h, else they will get an 'Adapting to Land' moodlet that lasts two days. When this expires, your Mermaid abilities disappear but you keep the diving skill. To avoid this, simply go for a Swim, Dive Underwater or Snorkel once in a while. You can also buy the 5,000 point Lifetime Reward Permanent Mermaid, which will prevent your Sim from ever losing Mermaid status to lack of Swimming.

Evil and Mean-Spirited Sims can click themselves to Summon Shark, but this doesn't really do much. Sometimes, a Shark won't even appear anywhere around you, and if it does, it may very well do nothing when it arrives. On my first try, a nearby Sim did pee himself in terror at the Shark that was already there, but that was the most I got out of it.

Because of Mermaids' inherent Diving Skill, you could go ahead and open all treasure chests that are openable based on Scuba Diving skill level and even unlock a private island pretty quickly. Click here to get the locations of Dive Spots, Treasure Chests, and Caves.

At present, it's very annoying getting around Isla Paradiso as a Mermaid because they prefer to swim everywhere, even with a boat for an option. The solution to this is to own a boat and select the 'boat here' option on the water near a place you want to go. If EA corrects this pathing issue, I'll remove this notice.

Mermaid Genetics work the same as usual. 100% chance of a Mermaid baby if both parents are Mermaids, 50/50 chance of a Mermaid Baby if only one parent is a Mermaid. You cannot be a Mermaid and another Occult at the same time, so with two Supernatural parents, it'd be 50/50 one or the other.

Mermaids do not have the Hygiene Motive, instead Hydration. Mermaids are always squeaky clean and get a +10 bonus from this at all times. Hydration means that once every so often a Mermaid needs to get wet, either via a shower, bath, or swim in the ocean. Mermaids will dry up faster in the sun, particularly when the temperature is 90 degrees or more when you have the Seasons Expansion Pack. Keeping hydrated in a bath but never going for a SWim will eventually cause a Mermaid to transform back into a normal Sim.

When the Hydration Motive begins to decay, you'll first have a Chapped moodlet with no mood effect, but at around 10% it will change to a -40 12h Flakey moodlet. If the Mermaid still doesn't seek water, a -80 Dehydrated moodlet will kick in, and the Mermaid will go unconscious. If you have other Sims under your control, you can easily revive them with a bucket of water. Nearby Sims may also help, with Good or Friendly Sims guaranteed to help, while Evil and Meanspirited Sims will simply walk by or enjoy the show.

All Mermaids' favorite foods change to Kelp, and they are capable of eating raw fish on the go - so can simply catch them underwater for a snack later. Mermaids are 25% less satisfied by normal Sims' foods. Kelp can be found underwater or at the grocery store.

Meeting and Befriending Mermaids
You can meet Mermaids while Diving, or out in the world. You can tell if a Sim is a Mermaid if their legs have scales while walking on land. Mermaids frequently visit Diving Spots that are used by the Scuba Diving Skill. Once you've met a Mermaid, they will appear in your relationship panel and you'll build a relationship with them.

Once you've got a Mermaid in your relationship panel, you can click them and use the option Signal Mermaid to blow a sea shell horn and get them to come visit you if they're available. This is only possible on land, unfortunately. Another way to befriend them is to build up relationship high enough and use the underwater conversation option 'Invite to Land'. If your relationship is high enough, they'll even come to your home so that you can perform better social options and boost the friendship faster. Both of these options are preferable to meeting many Mermen underwater and talking to them as they come, hoping to build a relationship. Focusing your effort is the fastest way.

Becoming a Mermaid: Mermadic Kelp
When your friendship with the Mermaid is at 70% or higher, you can use the underwater conversation option 'Ask about Fish Parts' which cannot be done on land. If successful, the Mermaid will give you some Mermaidic Kelp, which will transform the Sim that eats it into a Mermaid. You can ask for these repeatedly, just make sure the conversation doesn't get boring. That way, your one Sim can use his Mermaid buddy to help you turn the entire family into Mermaids.

If you don't feel like befriending a Mermaid, you can get Mermaidic Kelp as a LTR for 25,000 Lifetime Happiness Points. This kelp will be placed in your inventory and is transferable between Sims.

Mermaid's Secret Island is Revealed

Mermaid's Secret Island
One of the eight uncharted islands you can unlock are found through Mermaids. You need to get a Mermaid to be your Best Friend, then hang out with them. Simply idle, and eventually the Mermaid will come up and offer to show you the location of the Mermaid Secret Island. When you arrive, your Sim will claim ownership. There is no treasure chest on the island, but there is a nice 30x30 plot of land on which to build a lovely home. Most of the island is blocked off by mountain, so there's not much to explore.

Changing Back to Normal
If you no longer wish to be a Mermaid, simply avoid swimming for about four days. A couple days in, a moodlet will appear telling you that the Sim is 'Adaping to Land'. When this expires, the Sim will revert back to a normal Sim. Potent Cure Elixir will also work to return a Sim to normal. When your Sim loses his or her Mermaid abilities, they will still keep the level 10 Scuba Diving skill experience they earned during the transformation.

Changing Tail and Shell Colors for Mermaids
You cannot edit a Mermaid's tail in normal Create-a-Sim. Instead, you need to buy or find a mirror and click it to choose the 'Change Scale Color' option. This will let you change what little you can about your Mermaids, but the scale colors are fully customizable so you can pick a color that you like.

I discovered a little while ago that it's possible to exit Origin while the game is starting up. When I've exited Origin, the game doesn't crash any more. One time I forgot to do it and I got the "low on memory" warning, so I know Origin is causing the problem.

My teen sim tried eating mermaidic kelp from LTR and even from other good mermaids but she still won't transform? It just says it's tastes good but I don't feel any different. She's human. What am I doing wroing? I took out all the mods that might be interfering.

Is your Sim a supernatural beast? If so, then it doesnt work but dont worry! You need a potion to turn the sim into back to human OR then with other sim ask them to be not anymore (Whatever they are) and your done :3

"salt water deficiency" mood let showed up on my sim. what does this mean ? will she change back in to a human if I don't treat it ? what will happen ?

Rebecca says...
Maria, a Mermaid Sim needs to swim in the ocean at least once every 48 hours, otherwise they'll get a "Salt Water Deficiency" moodlet. Within a day this will turn into "Adapting to Land" and when this moodlet expires, the mermaid will turn into a normal Sim. Hope this helps :)

When does the mermaid child gets it tail
The scales arrive as a toddler and the tail happens as soon as they are a teenager.

Thanks! I read through some of this, and now I know you cant make one in CAS. When I get Island Paradise, I'll just do testingcheatsenabled and meet all mermaids and befriend them. (And maybe even kill Salty. Or just make him good again. And get the kelp from Maya, because it was in iHasCupquake's LP. XD)

My mermaids can't hydrate using swimming in the ocean. I'm not sure what went wrong but it only hydrates them when they have a bath or shower not when they swim in the ocean. How do I fix this, can anyone help?

What diving spot are mermaids more common? I went to The Mermaid Grotto for obvious reasons, but didn't spot any. Is there a specific time to go. I dived at night because my sim is a vampire.

If you want good kelp, go to the babes on the beach household. One of them is a mermaid and she gives good kelp. But sometimes there all human, it changes all the time for me :( Has anyone tried the siren household? Its on a island in the middle of the ocean.

I've found that having a pregnant mermaid (by a human sim) eat kelp makes it more likely for the baby to be a mermaid. I haven't tested intensely though.

The same thing is happening to me! She wont become a mermaid! Shes just getting ill, and runs to the wc :( i have tried to eat the mermaidic kelt like 10 times! I got it from my mermaid boyfriend ( without cheat)

Nikka says...
Yes! I just got mine from my mermaid boyfriend. I asked Mia Azul (aka Ariel) if she would give me kelp and she did. But this time the message was different and she said if you want to be like me eat this kelp. But my sim's boyfriend said my legs are too superior and i'm more attractive than you. Maybe they gave us ***** kelp so we don't became mermaids?
Maybe?  Does this mean it finally worked?

Are you eating this on your home lot or trying on a community lot?
27th June 2013 3:50pm
Nikka says...
I tried on both a community lot and my home lot with my sims's boyfriend kelp. I tried Ariel's kelp on the beach and it finally worked the first time around
