Build, play, and learn together

The set invites constructive play that blends hands-on building with imaginative storytelling. The posable dragon mirrors action from the NINJAGO Dragons Rising universe, while the four ninja figures offer varied personalities for role play and teamwork scenarios.

This makes it easier to extend play sessions with new configurations and challenges, without overwhelming first-time builders.
