How to Become a Mermaid in Sims 4

The Sims 4, an ever-evolving simulation game from Electronic Arts (EA), has continued to charm players with its expansive virtual world, character customizations, and unique gameplay features.

Among the many features it offers, one of the most mystical and fascinating is the ability to transform your Sim into a mermaid. But how exactly can you achieve this aquatic transformation?

In this guide, we will delve deep into the waters of Sulani, exploring how to become a mermaid in Sims 4 and embrace the mystical life under the sea.

The Allure of Mermaids

Before diving into the tutorial, it’s essential to understand the appeal of mermaids in the Sims 4 universe. Just like in age-old folklore and stories, mermaids in the Sims 4 embody the mystery, beauty, and magic of the sea.

They bring a blend of human and aquatic attributes that not only offer unique gameplay experiences but also open doors to captivating narratives for your Sims’ lives.

Characteristics of Mermaids

  • Tail Transformation: When a mermaid Sim gets into the water, their legs transform into a beautiful, colorful tail, befitting the legends of these creatures.
  • Unique Powers: Mermaids possess unique powers, from the ability to call dolphins to controlling the moods of other Sims using their siren song.
  • Oceanic Needs: Unlike regular Sims, mermaids have hydration needs, and the sea is their source of sustenance and rejuvenation.

Diving into Sulani

To begin your journey of transformation into a mermaid, the first step is to explore the tropical paradise of Sulani, which was introduced in the Sims 4: Island Living expansion pack.

Getting the Expansion Pack

Without the Island Living expansion pack, your Sims cannot become mermaids. You can purchase and download this expansion from the official Sims 4 website or through game distribution platforms like Origin.

How to Become a Mermaid in Sims 4: The Transformation Steps

Now that we’ve set the stage let’s dive into the step-by-step process of turning your Sim into a mesmerizing mermaid.

  1. Mermadic Kelp: This magical seaweed is the key to your transformation. There are several ways to obtain Mermadic Kelp:
  • Purchase it from the rewards store for 500 satisfaction points.
  • Explore cave systems in Sulani. Sometimes, your Sim can find Mermadic Kelp as a treasure.
  • Befriend a mermaid. They might gift your Sim with this magical seaweed.
  1. Consuming the Kelp: Once you have the Mermadic Kelp, make your Sim eat it. Immediately after consuming, they will feel a bit “strange,” hinting at the upcoming transformation.
  2. Dive into the Waters: Have your Sim swim in the ocean. As they touch the water, their legs will transform into a tail, completing their metamorphosis into a mermaid.

Reversing the Mermaid Transformation

While the life of a mermaid may seem enchanting, some players might want to revert their Sims back to their human forms. To do this:

  • Consume another piece of Mermadic Kelp.
  • Without swimming for an extended period, your Sim will lose their mermaid status.

Embracing the Mermaid Lifestyle

After transformation, it’s crucial to understand the new needs and lifestyles of mermaids to ensure their happiness.

  • Hydration: Regularly swim in the ocean or take showers to keep your mermaid Sim hydrated.
  • Utilizing Powers: Make the most out of your mermaid’s unique powers. Interact with marine life, sing the siren song, and explore the vast oceans.


The Sims 4, with its rich and diverse gameplay, offers players myriad opportunities to craft unique stories.

Transforming your Sim into a mermaid and exploring the marine world is just one of the many tales waiting to be told.

Whether you’re a longtime player or new to the game, the magic of mermaids is waiting for you in the tropical paradise of Sulani.
