Many sets offer water-themed play like floating boats, launchable water elements, water-park features (slides and a whirlpool), and aquatic display details such as swimming fish, swaying coral, and water-splash elements.
Some play-focused boat sets are designed to float and to launch water elements during play, allowing water-based actions as part of the set experience.
Adult display aquarium and diorama kits often include mechanical or posable features such as a swimming fish, swaying coral, an opening treasure chest, removable cabin roof, and posable bird head or claws for display flexibility.
Many sets include printed step-by-step instructions plus access to the LEGO Builder app, which offers digital building guides with zoom, rotate and 3D viewing tools for a guided building experience.
