In the Sims 3 Island Paradise your sims can become a mermaid. In order to become a mermaid, a mermaid must give you the mermaid kelp or in life time rewards you can purchase it. Your sim must be human to become a mermaid (not a vampire, wolf, etc.)
To become a "half-time mermaid," you can start by embracing aquatic activities like swimming or snorkeling, and incorporating mermaid-themed elements into your life. Consider joining a mermaid swim class or community, where you can learn to use a mermaid tail and connect with others who share your interest. Additionally, you can express your mermaid identity through art, fashion, or social media, allowing you to enjoy your mermaid persona both in and out of the water.
Mermaid Melody first aired on April 5, 2003.
