LEGO is giving adult builders a vibrant, maintenance-free world to escape into with the new LEGO® Icons Tropical Aquarium building set. This massive, display-worthy model is a brick-built interpretation of a thriving underwater environment, perfect for bringing a piece of meditative charm to any home or office without the hassle of real fish.
The set is a monumental undertaking, comprising 4,154 pieces that create one of the most visually saturated models of the year. The assembly allows you to construct richly colored coral, anemones, and four different model fish. The final structure measures over 20.5 inches wide, encased in a sleek black frame that mimics a real aquarium.
The set’s defining characteristic is its kinetic charm. Builders can activate hidden levers, cranks, and dials that bring the scene to life: a swimming fish traverses its path, a crab emerges from a cave, and coral sways in the currents. This clever analog mechanics transforms the set into a functional piece of kinetic sculpture.
The LEGO® Icons Tropical Aquarium (10366) will be available for LEGO Insiders on November 13, 2025, with general availability starting November 16th. The set is priced at $479.99 USD.
