In this guide, you will come to know how to turn your Sim into a mermaid in The Sims 4 Island Living.
First, you have to find and eat pneumatic kelp before going into the water. To get this kelp, you need to go to a rewards store to get the satisfaction point perks and buy nomadic kelp, which will cost you five hundred satisfaction points, as shown in the image below.
Now you need to head towards the Mua Pel’am go to the left side of the waterfall, where you will find a cave. You have to go inside and interact with the cave. First, you have to search for wildlife, discover the natural wonders, and then travel to cave water and see that your Sim will get some water.
After that, you need to find a dolphin and interact with it and then befriend them by talking with them. You can also feed a few treats, and then you need to ask them to perform the fetch trick in which the dolphin will scour the water for treasure, and it will find you nomadic kelp and other things, as shown in the image below.
When you have the nomadic kelp, you have to eat it, and you will receive a moodlet that will energize you for twenty-four hours, so now you have to enter the water within the twenty-four hours when the moodlet is active, and you will transform into a mermaid.
