Mermaid World: Koi Mermaid


The Koi Mermaid is a three trait mermaid in Mermaid World. It combines three different colors to create this brand new mermaid for your game. You’ll notice that most of the times, the colors the mermaid represents are seen through their designs and this mermaid’s color the same as her representing colors.

Antique dishes that have drowned from above become a collage of colors on her tail. The mosaic of shapes suggest a diverse love of these fragile fragments.~ Game Description
