Mermaids are a life state that were introduced in The Sims 3: Island Paradise and reintroduced in The Sims 4: Island Living. They are creatures of the ocean and water, that can be encountered diving or just taking a stroll by boat in the sea. They are also capable of living on land.

The Sims 3: Island ParadiseEdit

Becoming a MermaidEdit

A Sim can become a mermaid by ingesting mermadic kelp, which can be obtained either by becoming good friends with a mermaid and using the "Ask About Fish Parts" interaction while both the Sim and the mermaid are underwater, or purchasing the Mermadic Kelp lifetime reward for 25,000 lifetime happiness points. Note that other life states cannot become mermaids even if they eat the mermadic kelp. They have to become normal Sims before they can turn into a mermaid.

Mermaid is a genetic life state. There is a 50% chance a child will be a mermaid for each mermaid parent. If both parents are mermaids the child will be 100% mermaid.

Even if Supernatural is installed, mermaids cannot be created in Create a Sim.


While in water, Mermaids have a colorful scaly fish/dolphin tail in place of legs. Males have a tail with a straight fin like a shark, and go shirtless, while females wear a seashell bikini top and have tails that end in a classic dolphin-shaped fluke. On land, a Mermaid's tail will transform into a scaly pair of legs of the same color. Mermaids have their scaly legs from toddlerhood, but their legs won't transform into a tail while in water until the Sim is a teenager.

The color of a Mermaid's scales and (if they are female) seashell bikini top can be customized by using the "Change Scale Color" interaction via mirrors.


Mermaids needs vary from regular Sims in two ways:

  • Hydration - In place of Hygiene, there is a "Hydration" need, similar to Water for a PlantSim. This can be satisfied by swimming in the ocean or a pool, using the shower or bathtub, or relaxing in a hot tub. If The Sims 3: Seasons is installed, they can also hydrate by standing in the rain. Dehydration will cause the Sim to dry out, giving them a negative moodlet. Eventually they will pass out, and if another Sim does not splash water on them, they will die.
  • Hunger - Mermaids don't get much energy from normal meals. Instead, they require fish and kelp. Fish can be caught from fishing or while scuba diving, and can be eaten raw. If a Mermaid has the Vegetarian trait, eating fish will make them nauseous. Kelp can be harvested from diving areas or purchased from the grocery. If a Mermaid's hunger need is very low, eating two pieces of kelp is enough to fully replenish it.

Even if a Mermaid is well hydrated, they need 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. Purchasing the "Permanent Mermaid" lifetime reward will prevent the Mermaid from losing their occult status.

If a mermaid is near a fireplace or in the sun for a while they will get a moodlet causing their Hydration need to drop faster than usual until they move away and the moodlet expires. The moodlet lasts three hours.


Mermaids have various water-related special abilities. They can breathe and stay underwater indefinitely, and will not get the "Depressurising" moodlet when returning to the surface. This makes the Steel Lungs lifetime reward useless for them. Mermaids swim faster than normal Sims on the surface and underwater. Once a mermaid becomes a teenager they will automatically maximize their Scuba Diving skill. Mermaids do not need umbrellas when it rains [TS3:S], and they will get a positive moodlet when they get soaked.

Like normal Sims, mermaids who possess a conch shell are able to summon another mermaid they have met. Mermaids with the Mean Spirited or Evil trait are able to summon sharks to attack other divers. Mermaids are safe in their aquatic environment and will not be attacked by sharks, however they can be attacked by the cave monster. If mermaids are on a boat, they will not be attacked by the Kraken.

Hidden IslandEdit

One of the hidden islands in Isla Paradiso can be unlocked by becoming good friends with a mermaid in one of the diving areas. After befriending them, the mermaid will come up and offer to show the location of mermaid's secret island, and then the player will unlock it.

Mermaids will return in The Sims 4: Island Living.

Becoming a MermaidEdit

Sims can become Mermaids by ingesting Mermadic Kelp, which can be acquired through searching through the cave on Mua Pel'am or can be retrieved by a Dolphin. Once a Sim ingests Mermadic Kelp, they will be given a "Strange Sensations" +3 Energized moodlet.

Unlike Island Paradise, in Island Living mermaids can be created via CAS under occult state.

Mermaids are a genetic life state. There is a 50% chance a child will be a mermaid for each mermaid parent. If both parents are mermaids the child will be 100% mermaid.


Mermaids have an array of different looks. Within CAS, players can give them four different tails with many different colours, and multiple tops for female mermaids. Mermaids can also have different skin tones of their own, they can have special scales on their face, different eyes with unique eye colors, and a new set of teeth that resemble shark teeth.

Mermaids resemble regular Sims on land, however once they enter a body of water, either the ocean, pools, or bathtubs, they will grow a tail.

The color of a Mermaid's tail and other features can be customized under "Change Sim".


A Mermaid's needs are different to a Sim in one way:

  • Hydration - In place of Hygiene, Mermaids have Hydration. Mermaids need to regularly hydrate their skin to stay happy, they can satisfy this need by drinking water, taking a bath, and going into the pool or ocean. Hydration is also needed to use their mermadic powers. Being out in the sun drains their hydration need faster than at night


Mermaids have an array of powers that are based around water. Depending on if they have a good or bad trait; Mermaids have different powers, however if Mermaids have neither trait, they have all the powers. Mermaids are naturally great swimmers, so that they can swim at fast speeds, as fast as an Aqua-Zip.

Mermaids can sing "Siren's Lullaby" to Sims:

  • Aegean's Question (-30 Hydration)
  • Charmer's Lullaby (-30 Hydration)
  • Inspiring Berceuse (-30 Hydration)
  • Night's Requiem (-30 Hydration)

Mermaids have also other powers on Sims and the ocean:

  • Mermaid's Kiss (-30 Hydration): A Mermaid's Kiss grants whoever is kissed the "Aquatic Breath" moodlet, which temporarily gives Sims the ability to dive underwater for longer periods of time.
  • Aquatic Lure (-30 Hydration): Calls fishes to nearest water for fishing.
  • Call for Dolphins (-30 Hydration): Calls for Dolphins and Dolphins the Mermaid is friends with.
  • Siren's Call (-100 Hydration): Mermaid's can lure a Sim to them in the ocean and once near, the Mermaid will dive underwater and drag the Sim down into the water. If repeated enough times can cause the Sim to drown.
  • Summon Ocean Threat (-30 Hydration): Mermaids sing a haunting song that summons a black mass underneath their target that swallows the Sim. If repeated enough it can cause the Sim to drown.

Conch ShellsEdit

Mermaid's can utilize conch shells that can be found at the beach to access other abilities; Mermaids can blow through a conch shell which will attract nearby Mermaids to the Sim's location.

If Seasons is installed, Mermaids can use the conch shell to summon a thunderstorm.

Turning into a HumanEdit

Mermaids, who wish to no longer sprout a tail when they go into the water, can become a regular Sim by ingesting two Mermadic Kelps in a row. After eating two of them, the Mermaid will now be a regular Sim.

Poseidon's Fury

Poseidon's Fury

  • The mermaid is mentioned in The Sims Medieval, in one of the random events in docks.
  • The statue "Poseidon's Fury" and the "Trident's Spring Fountain" from The Sims 3 Store both show mermaids outside of The Sims 3: Island Paradise. There is also a mermaid statue in Ambitions named Siren's Call.
  • The Sims 3: Seasons has two clothing pieces and a hairstyle which have a look akin to that of a mermaid.
    Trident's Spring Fountain

    Trident's Spring Fountain

  • Just like other life states, Mermaids cannot become another creature without having their Mermaid status revoked first.
  • Mermaids cannot skinny dip in a hot tub, but can still WooHoo.
  • Some mermaids can have pale skin like vampires. In Island Living, they can have other skin tones based on ocean colors.
  • Mermaids cannot get a tan if they have the pale mermaid skintone. Mermaids with other skintones, like Maya Ocean, will get tanned.[TS3:S]
  • Mermaids will get a positive moodlet when being soaked, thus eliminating the need for an umbrella.[TS3:S]
  • Cats are twice as likely to follow a Mermaid than any other Sims.[TS3:P]
  • Pregnant Mermaids can swim at the water's surface, but cannot visit scuba dive sites for the duration of the pregnancy.
  • If a Mermaid goes into labor, they can't have their baby in the sea, they must go to land to give birth, and Mermaid babies must grow on land.
  • There are several minor references to Disney's The Little Mermaid. Some premade mermaids are based on characters from the film, such as Triton King and Mia Azul. When a Sim explores an underwater cave, sometimes a message appears saying, "(Sim's Name) has not found anything big, but he/she found a dinglehopper," or "how many wonders can one cavern hold?"
  • Mermaids cannot be saved to the bin, created in Create a Sim, nor shared on The Sims 3 Exchange. This is due to the fact that developers wanted them to be only special creatures. However, they can be saved and created in Create a Sim in The Sims 4: Island Living.
  • Mermaids cannot surf on the wave station.
  • Mermaids cannot become zombies.[TS3:SN]
  • Trident's Spring Fountain is similar to a female mermaid's tail.
  • The two pieces of mermaid decor in The Sims 3: Seasons named Maya the Mermaid and Mia the Mermaid share names with the two female mermaid NPCs in Isla Paradiso.
  • Zombies will never attempt to eat a mermaid's brain.[confirmation needed][TS3:SN]
  • While Mermaids in Island Paradise had a few benefits and abilities. Mermaids in Island Living are the first to have proper powers that mimic their mythology, such as Mermaid's Kiss and Siren's Call.
  • Unlike in Island Paradise, Mermaids in Island Living that enter bathtubs will have their tails laying outside the tub.
  • Mermaids in Island Living have a twitch where they will randomly imitate a dolphin squeak.
