lol water surprise

Most sets are labeled for children Ages 4 and up.

The dolls are commonly made from ABS (Acrylonitrile Butadiene Styrene) and PVC (Polyvinyl Chloride).

Sets commonly include a doll plus clothing and accessories such as an outfit, shoes, a bottle, extra accessory pieces, collectible Lil Sister figures, confetti or other unboxing elements, squishy and classic water balloons, and sometimes stickers.

Most entries include a choking-hazard warning for small parts—often listed as 'Choking_hazard_small_parts'—so these toys are not suitable for children who put small items in their mouths.

Mermaid and tween dolls often feature color-changing tails that react in cold water, movable fins, and articulated bodies for posing during bath-time play.

The packaging is reusable: the carrying ball doubles as a clamshell display so kids can carry and showcase the baby-mermaid dolls.
