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). Featuring a posable mech, ninja car, spider toy, and a golden-sword display, kids can enjoy hours of ninja adventures. This cool ninja toy is specially designed to give young builders aged 4 and up 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 start building. LEGO 4+ sets are the perfect way for adults to enjoy building with kids. It's quick and easy to get started – as well as a step-by-step paper guide in the box, this set comes with Instructions PLUS on the LEGO Building Instructions app. This interactive guide includes zoom, ghost and rotate tools for children to get the most from the building process.
