Product Information

Full details

The LEGO Friends Mermaid Roller Coaster (42703) is designed for young builders and fans of amusement parks who enjoy creative construction and imaginative play. Its primary benefit is a highly interactive, functional roller coaster model that offers deep playability through its rotating pool and multiple themed characters. A notable caveat is the set's size; at 52 cm wide, it requires a significant amount of display or play space to accommodate the full track layout.

Does this set include motorized components?

Is this set compatible with other LEGO Friends sets?

Yes, the hair pieces are standard LEGO connections and can be swapped with most other mini-doll hair styles.

What is the best way to handle the delicate pieces?

Troubleshooting

Roller coaster car stops mid-track

Check all track connections for gaps and ensure the track is fully seated into the support columns.

Rotating pool is difficult to spin

Check the underside of the base to ensure no stray pieces or debris are caught in the rotation mechanism.

Mini-dolls don't fit securely in the seats

Ensure the mini-doll's legs are pushed firmly into the studs inside the coaster car.

Pros and Cons

Engaging mechanical movement for the roller coaster track
Detailed character set with exclusive opalescent hair pieces

Setup, Compatibility & Care

For the best assembly experience, download the LEGO Builder app to view the 3D instructions, which can be particularly helpful when aligning the complex curved track pieces. Ensure you build on a clean, hard surface to keep track of small pieces like sea animals and accessories. To clean the set, use a dry, soft brush to remove dust from the crevices of the coaster track. Avoid using water or liquid cleaners, as these can affect the friction of the mechanical parts and the finish of the specialized opalescent hair pieces. If the track becomes misaligned, simply lift the affected section and press firmly back into the base clips until you hear a distinct click.
