LEGO DUPLO 10435 Ariel's Magical Underwater Palace

The LEGO DUPLO 10435 Ariel's Magical Underwater Palace invites toddlers into the undersea world of the Disney Junior show Ariel, with a bright, chunky palace that is made for little hands.

Ariel gets ready in her bedroom before heading to the spinning dance floor, where Fernie and Sebastian strike up a tune on their musical instruments. A movable swing adds another play feature, and there are plenty of accessories to spark stories about Ariel and her friends.

The set comes with two DUPLO figures, Ariel in her mermaid tail and Fernie the merman. Role-playing their adventures is a gentle way for young children to explore friendships and feelings, while pushing, spinning and clicking the large bricks together helps build dexterity and hand-eye coordination.

At 116 pieces with an age rating of 2+, it is a confident first step into Disney play for pre-schoolers, and DUPLO bricks also connect with standard LEGO bricks as children grow. It would make a cheerful birthday or Christmas present for any little mermaid fan, and we love how much variety is packed into such an approachable build.

Released in 2024, this palace has now been retired by LEGO, so we expect remaining stock to become harder to find.
