Mermaid Gabby’s Aquarium Adventure (11204) is a make-believe toy for kids aged 4 and over who are fans of sea creatures, aquarium animals and DreamWorks Animation’s Gabby’s Dollhouse: The Movie.
This LEGO® Gabby’s Dollhouse playset is packed with vibrant features and familiar characters, including a Gabby minidoll in her mermaid outfit, and MerCat and Jellyfish figures. Kids can join Gabby and her pals to explore a colourful underwater environment filled with shells, plants and sea life. There’s lots to discover, including a slide, a giant bubble that MerCat can 'float' in, and coral that moves to reveal a hidden treasure chest. The set comes with colourful pictorial instructions, a large Starter Brick and separate bags containing 1 buildable model per bag to make creative construction fast and fun for little builders.
LEGO sets for ages 4 and over are the perfect way for adults to share in the building fun with kids. Set contains 103 pieces.
