Setup: Assembly Instructions
Follow these steps to assemble your LEGO DUPLO Ariel's Undersea Castle. Ensure all 35 pieces are present before beginning. Adult supervision is recommended for younger children.
- Unpack Components: Carefully remove all LEGO DUPLO bricks and figures from the packaging. Lay them out on a clean, flat surface to easily identify each piece.

- Construct the Main Castle Structure: Use the various colored bricks to build the castle walls and archways. Refer to the visual guides for brick placement.
- Add Interactive Elements: Integrate the spinning platform for Ariel and the blue slide for Flounder into the castle structure. Ensure these elements are securely attached and can move freely.
- Place Decorative Pieces: Attach the castle turret, seaweed elements, and other decorative pieces to complete the undersea castle theme.

Maintenance
To ensure the longevity and hygiene of your LEGO DUPLO set, follow these maintenance guidelines:
- Cleaning: Clean LEGO DUPLO bricks and figures with mild soap and lukewarm water. Rinse thoroughly and air dry. Avoid using hot water, harsh chemicals, or abrasive materials, as these can damage the plastic.
- Storage: Store the set in a clean, dry place away from direct sunlight and extreme temperatures. Keeping the pieces in a designated container will help prevent loss and damage.
- Inspection: Periodically inspect all pieces for any signs of wear or damage. Discard any broken or heavily worn pieces to ensure safety.
Troubleshooting
Here are solutions to common issues you might encounter:
- Missing Pieces: If you find a piece missing, double-check the packaging and play area. For genuine missing parts from a new set, contact LEGO Customer Service.
- Difficulty Assembling: Ensure you are following the visual instructions carefully. DUPLO bricks are designed for easy connection; if a piece doesn't fit, verify it's the correct piece for that step.
- Loose Connections: If bricks feel loose, ensure they are fully pressed together. Over time, some wear may occur, but DUPLO bricks are generally very durable.
