What Makes this set WOW?
Elevator mechanism with a crank: An integrated system of gears allows for smooth transport of the wagons to the top of the structure, which teaches children the principles of mechanics in a practical way.
Semi-transparent Azure-colored tracks: The use of unique, transparent track elements gives the queue lightness and imitates driving inside an impressive water tunnel.
Interactive model of a sea reef: The ride includes mechanical features, such as pop-up dolphin figures and an opening clam, activated by the passing trolley.
Exclusive mini-doll figures with nautical design: The set includes unique characters in pearl-finish and scale-print outfits, complete with rare accessories such as iridescent tiaras and fins.
