Kids can recreate the stories of Season 2 of the Ninjago Empire of Dragons series with Sora's Elemental Ultimate Robot (71807) adventure toy. The cool robot has adjustable arms and legs that can be bent into spectacular battle poses, plus a huge sword, a spinning blade and a driver's seat that fits the ninja minifigure. This never-before-seen, customizable robot lets kids build their own robot! Detachable legs, arms and torso can be combined with 2 other robot parts: Cole's Elemental Ground Robot (71806) and Kai's Elemental Fire Robot (71808) (sold separately). Kids can enjoy hours of fun swapping and matching parts to build a unique action figure. The ninja toy includes 2 minifigures - Sora with 2 katanas and a Wolf masked warrior - so kids can play out exciting ninja action. The set can be built using the LEGO Builder app, which guides you and your child through an easy and intuitive building adventure.
