Plantable Mermaidic Kelp

As you’d already be aware about, mermaidic kelp is used to turn your sims into mermaids, but this custom creator has overridden the earlier mod and this plantable kelp can now be planted anywhere and harvested just like a regular plant, and it’d continue to do its original task of turning sims into mermaids. You do require Island Living for this mod to work, though.

51. Summon Ocean Threat

Summon Ocean Threat

Mermaids are harmless creatures, but what if you could turn them into sinister characters who can summon deadly things from the ocean, and anyone who crosses their path would regret it?

This mod allows you to modify your mermaid’s harmless nature and whenever they are in water, this mod is activated. Your mermaid can even invite a sim over and sing to them to the depths of the ocean.

52. Mermaid Lifestate 2.0

Mermaid Lifestate 2.0

Earlier mermaids weren’t a part of the Sims 4 base game, but now they are and to become a mermaid, your sims must study the mythology of mermaids. Once they do so, they can transform themselves using the Moonpool. Since this mod was released before Island Living, it would not be updated any further, but it’s still an exciting feature. 

53. Stronger Mermaid Buffs

Stronger Mermaid Buffs

Sims 4 has always emphasized the importance of buffs and how your sim’s emotions have an impact on them. With this mod, a mermaid’s song would increase the buffs to a +10 instead of +2, of the sim listening to the song.

However, the game would show an increase of +2 only, but it’ll work as a +10. The creator is working on this issue. Your mermaids can now help other sims through this mod. 

54. Mermaid Babies

Mermaid Babies

You’d have noticed that your mermaid sim’s baby is always wearing the same onesie, because there aren’t a lot of options for baby clothes. However, this modder has come up with a collection of Mermaid babies that offers the babies a onesie resembling fish scales.

There are 3 categories to choose from: alien babies are green, boys blue, girls pinky-purple. So now your mermaid baby can also have a wardrobe of their own.

55. Swim Around in Pools

Swim Around in Pools

Now your mer-sims can also swim in pools, instead of just oceans or other large water bodies. However, it’d be excellent if the pool has an irregular shape and isn’t small, giving your mermaid area to swim and to go wherever they want to. 

56. Leg Scales for Mermaids and Chest Scales for Merman

Leg Scales for Mermaids and Chest Scales for Merman

Unlike Sims 3, this version of the game doesn’t offer the feature of leg scales on your mermaids, but you can still download this mod to get that feature. There are 22 swatches and both the leg and chest scales can be used for males or females, it’s up to you. You can even match them to your sim’s tail.

57. Merfolk Cove Lot Trait

Merfolk Cove Lot Trait

If you’ve played with Vampires, then you’d know about the Vampire Nexus and how all the vampires gather on that particular lot. Well, this mod is similar to that, but instead of vampires, mermaids come together on this cove lot.

This place would feel like home and give your sims a chance to gain the other mer-sims’ trust. It’ll also have an effect on their mood buffs.

58. Three Mermaid Aspirations

Three Mermaid Aspirations

Your mermaid sims can now enjoy three new aspirations: Ariel, Mermaid Experience, and Siren with this mermaid mod. The Siren Aspiration would make your sims deviant and their reward trait would be “hypnotizing.” Siren mermaid are the ones who lure other unfateful sims to their doom.

The Ariel Aspiration follows the Little Mermaid story and allows your sim to be a mermaid as well as a regular sim. The Mermaid Experience Aspiration is all about gaining more knowledge about being a mermaid. As soon as this aspiration is complete, they’ll become part of nature.

59. IL – Tweaks and Fixes

IL - Tweaks and Fixes

This CC pack includes various small mods that improve Island Living, but you’d have to download the XML injector for some of these mods. Features, such as Cryogenesis, Full Weather Control, Powerful Siren Song, and Toggle Mermaid form are available in it.

60. Mermaid Bloodlines

Mermaid Bloodlines

Till now, Sims 4 only had bloodlines feature for spellcaster sims, but this wonderful modders has come up with bloodlines for mermaids as well. But, you’d need MAL22’s Trait Tracker for the mod to function, and City Living for the singing skill.

Your mermaid families would have weak, strong, and ancient bloodlines and it affects their singing, fitness, hydration decay, and hydration drop.

So a sim with a weak bloodline would have 10% of each feature, while the one with strong bloodline would enjoy 20% of this and the ancient bloodline sims have 30% of these features, except hydration drop. Hydration drop would become 50% slower in their case.

61. IL – Sirens

IL - Sirens

Sirens are the opposites of mermaids, but in Sims 4 you’d need this mod to enable their deadly side. It’s essential to have XML Injector and Death Interactions for this mod.

For transforming your mermaid into a siren, purchase the Siren Kelp from your sim’s PC and once they consume it, their blood thirst would increase. Sirens can seduce other sims to drink their blood or eat them whole, and they can also drink from vampires.


These are all the Sims 4 mermaid mods that offer custom creations related to appearance, traits, build/buy mode and much more. No aspect of your mer-sim’s life would be left untouched if you download these mods.

All of them contribute to the gameplay in some or the other way, and it’d be a tough decision to decide which one to select. So good luck!
