Description

A cavern instead of a castle

Unlike many other Disney Princess sets built around a castle or a large outdoor scene, this one focuses on an enclosed, glittering underwater cave. At 152 pieces and two minifigures, the build stays compact, putting its attention instead on details such as crystal formations and hidden corners within the cavern itself. That fits the Ariel story, where underwater worlds and hidden treasures play a central role, giving this set a quieter, more intimate scene than a typical castle build.

Yellow, turquoise, brown and trans-pink

Yellow, Dark Turquoise, Reddish Brown and Trans-Dark Pink combine into a palette that strongly evokes underwater light, coral and sparkling crystal. The transparent pink delivers the crystal effect the set is named for, while Dark Turquoise carries the water and surrounding cavern. Yellow adds bright accents elsewhere, such as on jewellery or decorative details. The parts list on this page shows exactly how these colours are spread across the set's 96 distinct part types, and which pieces give the crystals their sparkle.

Two minifigures for a small underwater scene

With two minifigures included, there's enough here for a small scene within the cavern, such as a meeting between two characters from the Ariel story. Across 96 distinct part types and 152 pieces total, the build stays detailed despite its compact size, most visible in the many small crystal and decorative elements. That makes it appealing to children who enjoy playing with lots of small details rather than a few large structural pieces.

High part variety for a small set

96 distinct part types across only 152 pieces means many elements appear just once or twice, making the build feel more intricate and varied than sets built from long repeated runs of the same piece. Collectors specifically hunting for Trans-Dark Pink crystal elements or underwater decoration will find it worth a close look at the parts list. At the same time, the set's overall size keeps it manageable within a single afternoon session.
