Mermaids are mysterious creatures and so is this BABY born Little Sister Mermaid! She moves her coloured tail when it glides through water. As soon as she comes into contact with the cold, the colour of her outfit changes from pink-turquoise to turquoise-blue. How does she do it? Her long blonde hair has colourful strands. A cute crown adorns the hair, which can be wonderfully styled with the pink comb.
