Kids can recreate the stories of Ninjago Dragon Empire Season 2 with Kai's Elemental Fire Robot (71808) ninja toy. The robot's arms and legs are adjustable, so it can be set into spectacular battle poses, and the robot also has a driver's cab for the ninja figure and a large, golden sword to act out battle scenes against the wolf robot. This customizable robot lets kids build their own robot! Detachable legs, arms and torso can be combined with parts of 2 other robots: Cole's Elementary Ground Robot (71806) and Sora's Elementary Top Robot (71807) (sold separately). Kids can enjoy hours of fun swapping and matching parts to build a unique action figure. The red robot comes with 4 minifigures – Kai and Zane, both with katanas, Jordana with a sword and a Wolf masked warrior – so kids can play out exciting ninja action. The set can also be built using the LEGO® Builder app, which provides an easy and intuitive building adventure for you and the children.
