Kids can jump into the world of LEGO NINJAGO with Kai's Dragon Mech Battle Pack. The buildable dragon mech is fully posable and has a cockpit to place a minifigure inside. The three included characters - Kai, Sora and the Earth Monster - make it easy for children to jump into their own good-vs.-evil stories inspired by the Dragons Rising series. With 85 pieces, it's a great little set for younger builders aged 6+. Plus, the LEGO Builder app helps them along by letting them zoom and rotate the model as they go.
