[Top 15] The Sims 4 Best Mermaid Mods That Are Fun

Swim in the ocean and dive into the world of mermaids.

Make mermaids even better

Occult life states have always been fun to play with ever since the Sims came out. Looking at the Sims 4 with Occult life states in mind, they can seem lackluster. 

Modders have taken it upon themselves to improve existing Occult life states and add new ones to the game. Let's look at just one specific type of occult, mermaids. 

Mermaids in the Sims 4 end up stale after playing for a while. Mods can change the gameplay for mermaids, giving you, the player, more fun with the household. 

Which Sims 4 mods are the best to have for mermaids? Dive into the top 15 Best Sims 4 best mods that make mermaids more fun to play. 

15. Plantable Mermadic Kelp

Who doesn't want a farm of Mermadic Kelp?

Mermadic Kelp usually has a single purpose in the Sims 4, making your sims into a mermaid. You can't plant it to use it for anything else, but with the Plantable Mermadic Kelp, you can have an entire garden of it. 

From the mind of SrslySims, Plantable Mermadic Kelp is an override for mermadic kelp to be planted and harvested like any other plant. You do need to have Island Living before using this mod. 

Having harvestable mermadic kelp in your garden can have many fun advantages. Who doesn't love an army of mermaids and sirens?

14. Summon Ocean Threat

There are dangerous things beneath the ocean. Why not summon it? 

Depending on the lore you go off of for mermaids, they can be deadly. With Sims 4, mermaids are harmless to other sims. The mod Summon Ocean Threat changes the harmless mermaids and gives those unfortunate to cross paths with your mermaid/siren deadly results. 

The power Summon Ocean Threat was never deadly until PETSIMK created their mod. You can only utilize this ability in the water. 

This mod creates an extra element to what your mermaid can do. Invite your least favorite sim over to the beach and let your mermaid sing them to the depths of the ocean.

13. Mermaid Lifestate 2.0

There are many ways to become a mermaid, like the moonpool. 

Before we had Island Living, mermaids were not in Sims 4. Mermaid Lifestate 2.0 made mermaids possible for the base game. 

In this mod, you need to study the mythology of mermaids to become one. Once you have learned all you can, your sim can use the moonpool to transform into a mermaid. 

This mod came out before Island living. The modder has stated that it is broken and will not be updated. 

Playtesting this mod for a while, it still is fun to play with all the updates. There are a few bumps, but it doesn't take away from the mod.

12. Stronger Mermaid Buffs

With inhuman abilities you should have inhuman results. 

Sims 4 is a game based on emotions influencing everything the sims do; buffs are the result. With the mod Stronger Mermaid Buffs, your mermaid's songs will have an intense impact on the receiver's emotion. 

The moodlets caused by the mermaid's songs increase to a +10 from the typical +2. You may see the moodlet still state +2, but it will work as a +10. The modder is working on a fix for this issue. 

With Stronger Mermaid Buffs, your mermaid's abilities make more of an impact on others. Nothing like your sim helping lonely sims have a great date or making an already tense situation even worse.

The onesie your sim's baby wears is the only one they can wear unless you have the knitting stuff pack. A modder who goes by Mcrudd is known for making baby creations to give them more personality. 

Mcrudd has made a mod called Mermaid Babies, which gives your sim baby colorful mermaid scales as a onesie. There are three different categories and colors; alien babies are green, boys blue, girls pinky-purple. 

The scales are shiny and work well for a new mermaid baby. A step up from the typical onesie that your sim baby begins with.

10. Swim Around in Pools

Relax and swim around the pool for awhile. 

As Dory from Finding Nemo says, "just keep swimming." The Swim Around mod gives mermaids the chance to swim around in pools as they do in the ocean. 

While the action isn't exclusive to mermaids, it works well for mermaid stories. This mod works best in irregularly shaped pools. 

Keep in mind that this mod doesn't work well with small-sized pools. Sims don't have to swim in laps but can go anywhere they want to!

9. Siren Ears and Gills Mod

Whether your mermaid is a scary or an enchanting beauty, enahnce their look with scales and gills. 

When the topic of mermaids or sirens comes up, how do you see these creatures? Do you see gills or fish-like ears on these creatures? 

Most people will think of a more fishy look to these creatures. With the Siren Ears and Gills Mod, you get just that. 

This mod adds ears for all ages and genders with gills for teens and up. The modder states to use the smallest ear setting possible to avoid clipping issues.

8. Leg scales for mermaids + chest scales for male (22 swatches)

Why wear your heart on your sleeve? Wear your scales instead. 

If you remember mermaids back in The Sims 3, mermaids in their human form had scales showing on their legs. Sims 4 is missing, which can be a good thing depending on how you play with occult sims. 

Leg scales for mermaids + chest scales for male (22 swatches) mod brings that aspect into the Sims 4 with the addition of chest scales. Both the legs and chest scales and be used on male and female sims. 

The chest scales are seen better on male sims than on female sims. The best part is you can use them as tattoos or accessories.

You can find the Ariel aspiration under the Love category for those who have balanced being a mermaid and a regular sim. The levels keep true to the Disney movie The Little Mermaid.
