Let young builders dive into the world of LEGO NINJAGO with Nya and Arin’s Baby Dragon Battle. Designed for ages 4 and up, this starter set invites kids to build and role play, drawing inspiration from the Dragons Rising universe. The jet, two dragons, a cave hideout with energy crystals, and three minifigures offer a rich foundation for imaginative ninja adventures, all within a compact, kid-friendly build.

Inside the box, each bag reveals a guided build and a character, helping new builders jump into action quickly. A Starter Brick provides a partly constructed base, giving kids a gentle starting point and a sense of progress from the start. The set’s colorful bricks and chunky pieces are easy for small hands to grip, encouraging independent play as well as family building sessions.

What kids can do

  • Recreate scenes from the NINJAGO Dragons Rising series using approachable, age-appropriate builds and familiar characters.
  • Explore the energy dragon’s posable head, wings, and tail, and enjoy the ride with a minifigure saddle for quick storytelling twists.
  • Role-play with Nya, Arin, and the Imperium Claw General to spark dialogue, plotlines, and cooperative play.

Digital guidance and progress

  • The LEGO Builder app provides an intuitive, kid-friendly building experience with 3D views, zoom, and the ability to save progress.
  • Kids can experiment with different building approaches while caregivers can share in the journey and celebrate milestones together.

This set balances build time with open-ended play. The energy crystals add a splash of color to the cave hideout, and the two dragons bring dynamic motion to the imagination—all in a tangible, hands-on experience that invites storytelling and role-play.

Contains 157 pieces and scales to a compact play experience that kids can enjoy at home or on the go. The energy dragon measures over 5 in (13 cm) tall, 10 in (25 cm) long, and 9 in (23 cm) wide, delivering a satisfying presence during action-packed scenes.

Giftable, engaging, and easy to learn

  • Beginner-friendly build steps and a starter base help new builders feel confident from the first snap.
  • Bright colors and familiar NINJAGO characters make it a compelling gift for fans or curious newcomers.
