How to Become a Mermaid

Mermadic Kelp in The Sims 4
Mermadic Kelp in The Sims 4 is how you can turn your Sim into a Mermaid. It's always possible to change back to a regular Sim if you like.

You become a Mermaid by acquiring Mermadic Kelp. This is accessible via the Rewards menu for a mere 500 Satisfaction, a fact I find rather boring. You can also find the kelp while diving at deep water buoys and while exploring the "hidden" cave on the Island of Mua Pel'am. Both of these options rely on heavily random events in order to get a kelp, so you're probably better off buying them in the rewards store. However you may wish to acquire more, because they give pretty decent buffs.

When you eat the Kelp with a Sim, that Sim gets a 'Strange Sensation'. Enter the water, and you'll become a Mermaid. If you avoid the water for 24h your Sim will not turn. Simply head into the ocean and you'll transform into a Mermaid.

Playing a Mermaid

A Mermaid bathes in The Sims 4 Island Living Expansion Pack. This replenishes their Hydration.

When outside the water, Mermaids are mostly normally but may have access to a few of their powers. When they enter a body of water, they'll transform back to the form with a tail. Tail and fin colors can be customized in Create-a-Sim.

Mermaids are able to swim faster than a Sim with Level 10 Fitness. Their Hygiene stat is replaced with, "Hydration". This resource gradually declines while outside the water and will also deplete should you use any of the lackluster Mermaid spells that exist.

Mermaids won't dare to snorkel. Far too taboo, for them. They won't wear Scuba gear either, but they're willing to free dive and are very good at it. This makes up for the inability to snorkel, in my opinion. After all the best stuff is found deep on the ocean floor.

Note that there is no risk to your Sim if you let their Hydration go to 0. They won't die of it, they'll just stink really bad. I let mine go 24 hours and nothing happened, and she was still a Mermaid. So, how do we remove the Mermaid trait without cheating? Easy.

Changing Back to a Normal Sim

To revert to human form, you'll need two Mermadic Kelp. Eat one, and you'll get a buff - still a Mermaid, though. So it's safe for Mermaids to use them, if they only take one. However, if you eat a second it will remove the buff, and your Hygiene stat returns to normal. Enter the water, and you're a regular Sim. Return to Mermaid form by eating a kelp and answering the call of the oceans.

Mermaid Powers

A Mermaid catches a big fish in Island Living

The first because of their wonderful stamina in the water and bonuses when free diving, the second because they can use the Aquatic Lure spell to give a boost to a fishing spot anyone (in particular the Mermaid) can enjoy.

Important Note on Mermaid Powers: If your Sim is Good, at least 2 are not usable - Summon Ocean Threat and Siren's Call.

Call Azure Dolphin

Summon Azure Dolphin is a Mermaid Power in The Sims 4 Island Living
Azure Dolphin can be thought of as a way to get the minor benefits of a Dolphin buddy for your Mermaid.

Becoming good friends with a Dolphin (Soulmate) allows you to get a 5+ hour +2 Happy moodlet from being around them. There's probably more to dolphins than I know at the moment, but I'll add to this if that changes. Being a Mermaid does mean you don't have to go out of your way or wait for dolphins to spawn. You can tell your friend to come any time you're near open water.

Summon Ocean Threat

Summon Ocean Threat is a lot like Siren's Call, pulling a Sim underwater. However, it gives the target a +2 Uncomfortable Buff. I'm not yet sure if this could contribute to making that Sim drown.

Siren's Call

Siren's call is a spell in The Sims 4 Island Living
Siren's Call attracts Sims through the Singing. Do this in water where you're fully swimming but not in deep water. The Sim will be dragged under, and you'll regain +100 to all Motives.

This is seemingly only available in shallow water. With this Spell, The Sims sings seem dark-sounding melodies and proceeds to dash underwater toward their victim, pulling them under. This gives them a big +3 Stressed Moodlet, and tends to make Sims scared and leave the water. I don't know that this is really going to contribute to a death, though I kind of wish we had abilities that could be fatal. However, it's a draining spell, and Gives +100 to all the Mermaid's Motives.

Siren's Lullaby

The Siren's Lullaby is a category with four separate songs, each of which place a positive or negative Moodlet on a Sim that you targeted. All of their durations are 4 Hours.

  • Charmer's Lullaby: Removes Embarrassed Buffs and gives a +2 Flirty Moodlet
  • Inspiring Berceuse: Removes Uncomfortable Buffs and gives a +2 Inspired Moodlet
  • Aegean's Question: Removes Focused Buffs and gives a +2 Stressed Moodlet
  • Night's Requiem: Removes Energized Buffs and gives a +2 Sad Moodlet

Mermaid's Kiss

The Merfolk Kiss in The Sims 4 Island Living Expansion is a way for the Mermaid to make another Sim happy
Merfolk Kiss gives your target a Happy moodlet and says something about helping them to stay underwater longer.

Mermaid's Kiss give the target a +1 Happy moodlet. The way they do it when in the water is far more romantic, especially if it's two Mermaids doing the kissing.

Fishing Lure

Use this on a Fishing Spot. Now you are more likely to catch fish instead of seaweed. It also gives a boost to effective Skill Level for that Sim's Fishing.

Weather Control

If you have Seasons installed, clicking your Mermaid gives you a menu with three different types of weathers, perhaps changing throughout the year. I know that I was able to summon rain, a thunderstorm, or clear the skies. The Mermaid pulls out a conch to do this spell - it's pretty cool.

Hello! I know the expansion is extremely new, so people are still discovering things about it, but I wanted to just put the question out there in case anyone else is playing as well. Do mermaids always feel bad when they eat fish? It seems like mine doesn't like to either catch them or eat them, which seems kind of strange to me, but he gets an uncomfortable moodlet from eating fishy dishes and when he caught a fish it said he felt bad for harming a fish.
23rd June 2019 6:33am
It's the new trait 'ocean of child' that causes the discomfort and sad moodlet towards fish. I thought it was because they were mermaid too until I made a second one without that trait and they didn't mind fishing or eating fish. I hope that helps you! Smile
23rd June 2019 10:47am
Yes! I figured it out after a while, thank you! I had to remove it from my mermaid because it didn't make sense, although that's kind of a bummer :( I like that they would get enjoyment out of water activities. Ah well!

Mermadic Kelp in the rewards store? Not in my game.
23rd June 2019 3:26pm
If you have Island Living it will be there for 500 points.
23rd June 2019 10:28pm
Brian Z
I do, and it isn't.
24th June 2019 2:18pm
If you have a mod that adds lifetime rewards, or discounts them, etc. which hasn't been updated for Island Living, then the Kelp won't appear; I had a similar issue – I didn't know Seasons had any rewards until I discovered them through a cheat because of an outdated mod.
24th June 2019 6:04pm
Brian Z
Ah ha, that's why! I have the Immortal and Eternal Youth reward traits mod, that's probably what's doing it.
27th June 2019 2:26am
Brian Z
Sure enough, that's what it was, the Eternal Youth/Immortal mod.
27th June 2019 2:59am
Would it be possible to put up a gallery of all tail colors? I’ve been looking and I can’t find one.
23rd June 2019 9:18pm
One thing I'd like to add to Siren's Call, since it's only implied in the article:
The Sim this action is used on is indeed drained. Almost every parameter of the Sim is in the reds. Hunger adn Energy, though, is deep orange. Bad idea, if used on a Sim you control.
I tested it with my mermaid sim on his spouse to see, what would happen. She survived, so no worries.
And, well, it can be used as a killing move, since energy and hunger drop very low. Just wait until the victim drowns (or starves to death). Though AI controlled islanders will leave.

Also, all mermaid powers have a cooldown. Once used, you have to wait for a set amount of time before using the command again. It's even greyed out.
Also, Siren's Call can not be used on children. oNt sure if it can be used on teens, havn't tried it yet.
24th June 2019 12:18pm
Can you woodoo and marry a mermaid?
26th June 2019 2:44am
Yes you can woohoo, marry and have children with mermaids, with the children between a normal sim and a mermaid having a 50/50 chance at being either.
26th June 2019 6:00pm
I believe if you have the Forever Fresh trait, the hydration bar will not go down.
28th June 2019 5:17pm
It's worth mentioning that mermaids can't take sunbaths (which makes it impossible to complete one of the steps for the first milestone of the new aspiration without using cheats) and they can't use the new ocean ladder.
29th June 2019 7:41am
My mermaids are able to sunbathe!
1st July 2019 12:11pm
Mermaids can sunbathe as long as they have a natural skin color.
2nd July 2019 12:27pm
Finally another lifestate and it's a mermaid and pretty lackluster at that too Sad so how many more YEARS until we get college and a witch/wizard lifestate
5th July 2019 12:22am
Hi I was wondering do mermaids tails appear when in the hot tubs?
7th July 2019 11:23pm
If you get a sim to admit they're a mermaid, is anything supposed to show up to indicate it in the relationship panel? I had my sim ask a good friend if she was a mermaid, and she confirmed it. But nothing showed up in the relationship panel as it would for known aliens and vampires. If nothing changes in the relationship panel, is this just a question the same sim can ask the mermaid every couple of conversations and have it confirmed over and over again?
17th July 2019 11:18pm
Nothing shows in the relationship panel but what unlocks is your sim now will have the ability to see all the NPC mermaids with tails while they are swimming in the water. Up until you have the first mermaid finally confess that 'yes they are a mermaid'... the NPC mermaids just look like ordinary sims swimming with legs. This is why it seems as though there are no NPC mermaids in have to unlock the 'special' ability to see them in mer-form.
What also has unlocked is a new friendly social that now allows your sim to share the fact that mermaids exist (Friendly Social). Any sim your sim tells about the existence of mermaids will now also be able to see their tails in the water.
So you do not need to get other mermaids to confess, you'll be able to tell just by glancing at them in a swimming pool, ocean or a bath.
18th July 2019 11:40pm
Are mermaids immortal? Can’t find anything about it and my mermaid is an elder and just won’t die. She didn’t fulfill any aspirations that prolong life or anything... so I’m clueless why she’s still alive.
18th July 2019 6:34am
No, some sims can take up to 20 elder days to die, even longer if they have the Athletic Trait and/ or high fitness levels. And I'm assuming the mermaid does have high fitness levels from all the swimming they probably have been doing.
(Note: any sim type - not just mermaids- with the Athletic Trait will live longer in the elder stage, and again, longer yet of they have the Athletic trait + high fitness levels)
18th July 2019 11:43pm
Hm, she was way over the normal time so I gave her two mermaid things to eat. (Don’t know what they are called in English) She turned human and died right there of old age. So it must have had something to do with the mermaid occult.
19th July 2019 9:09am
I don't think it is an occult thing. The code is clear that longer elder stage is related to active trait and a combination of high fitness levels or completing the Body Builder aspiration. Changing the life state during elder-hood and then dying was probably just a coincidence tbh. I'll ask Carl to double check though.
