Ariel's Underwater Palace

The LEGO® Ariel's Underwater Palace (set 43207) is a 498-piece LEGO Disney Princess set released in 2022, opening Ariel's coral palace from The Little Mermaid for play and display. Three mini-dolls populate the throne room — Ariel, her sister Arista, and King Triton — joined by Sebastian, Flounder, and four dolphin figures. The palace features a slide, movable furniture, and large and small dolphin chariots, each pulling characters through the underwater scenery. A signature Disney Princess set that bundles family dynamics with the iconic dolphin chariots fans associate with Atlantica.
