Mermaid Gabby’s Aquarium Adventure (11204) is a playful underwater-themed LEGO® set designed for kids aged 4 and up who love sea creatures, aquarium fun, and DreamWorks Animation’s Gabby’s Dollhouse: The Movie. This colorful and imaginative playset features a mermaid version of Gabby in minidoll form, along with her friends MerCat and Jellyfish, as they dive into a vibrant ocean world filled with interactive surprises.
Children can join Gabby and her pals as they explore a whimsical seascape filled with shells, aquatic plants, and playful sea life. There’s plenty to discover, including a fun slide, a giant bubble that MerCat can “float” inside, and a piece of coral that moves aside to reveal a hidden treasure chest. Designed with younger builders in mind, the set includes a large Starter Brick and clearly separated bags for each buildable section, along with colorful, pictorial instructions that make building fun and approachable for preschoolers.
With 103 pieces, this set encourages storytelling, role-play, and fine motor development. It also offers a perfect opportunity for adults to join in and share the building experience with their kids. For even more fun, it can be combined with set 11205 (sold separately) to expand the undersea adventure into the three enchanting worlds from the movie.
