The Water Wonder Marina mermaid doll features blue hair with purple highlights, a glittered purple bikini top, and white ruffle detailing. Its tail transitions from lilac purple to blue when submerged in cold water. The waist is articulated, allowing the tail to move freely in water, making it suitable for pool, beach, or bath play. Designed for sensory exploration, the toy encourages mess-free discovery. The vibrant hair and bikini top support color-recognition activities during play.
