The L.O.L. Surprise Bubble Surprise features collectible Lil Sisters hidden inside a bubble-filled ball. To reveal the toy, pour water into the top of the ball, triggering a color-changing bubble reaction. Each Lil Sister has a distinct design with shimmering details and accessories. One variant, Lil Swan Star, changes color when bathed in cold water. For optimal bubble production, warm water at 98°F is recommended. The series includes 12 different Lil Sisters to collect.
