Discover a Vibrant Underwater World with the New LEGO® Icons Tropical Aquarium Building Set for Adults

Today, the LEGO Group unveils the LEGO® Icons Tropical Aquarium Building Set - a vibrant, brick-built interpretation of an underwater world, teeming with imaginative details and playful charm.

Designed with intricate craftsmanship, this set invites builders to explore the beauty of marine life through the limitless possibilities of LEGO bricks. Rotate the dials and crank to animate swimming fish, swaying coral, a crab emerging from an underwater cave, and an opening treasure chest. The set includes four model fish and features a variety of plants and coral, sea worms, an oyster shell with a pearl, sea snails, and air bubbles - all brought to life in a dynamic, interactive build.

Builders are invited to bring the tranquillity of the ocean into their homes, creating a striking centrepiece that sparks conversation and creativity. Whether displayed at home, brightening a workspace, or gifted to an ocean enthusiast, this 4,154 piece set is more than a model - it’s an eye-catching centrepiece that brings colour and calm to any space. No water required, no maintenance needed — just pure creative joy, one brick at a time.
