The L.O.L. Surprise Tweens Mermaid Lola Waves fashion doll features a color-changing tail that shifts from magenta to deep purple when submerged in cold water, including a light pink fin that also transforms. The doll has a movable fin that swings back and forth for dynamic play. Included accessories are sea shades, a sea shell tiara, and a pearl belt for styling. With articulated joints at the waist and legs, the doll can be posed sitting or standing for display. This doll is part of a series of four—Cleo Clove, Lana Marine, Serena Finn, and Lola Waves—each with unique mermaid designs.
