Kids can develop their building skills and play out fun scenes from Season 4 of the LEGO NINJAGO TV series with Jay’s Electro Mech (71740) building set. Featuring a posable mech, ninja car, spider toy, and a golden sword display, kids aged 4+ years old will have hours of ninja adventures. This cool ninja action figure toy is specially designed to give young builders a brilliant play experience. Inside the box, each bag of bricks has a complete model and character to build so kids can quickly get the action underway. There is also a Starter Brick to provide a partly constructed base to begin building.
