Mermaids are mysterious creatures, and Little Sister Mermaid is no exception. She beats her colourful tail to glide through the water. As soon as she comes into contact with the warm liquid, the colour of her outfit changes from pink and turquoise to turquoise and blue. How does she do it? Her long blond hair has colourful streaks. A cute tiara decorates her hair, which can also be styled beautifully using the pink comb.
