An ethereal underwater dreamscape. A mermaid with a shimmering, iridescent tail and long silver-gold hair drifts gracefully through a forest of giant, softly glowing kelp and crystalline coral formations. Sunlight filters from above in shimmering columns, illuminating schools of delicate, translucent fish. Painterly watercolor animation with gentle ink outlines, a soft marine color palette of blues, greens, and purples. Magical and serene atmosphere.
