Kids can develop their building skills and play out fun scenes from Season 4 of the LEGO NINJAGO TV series with Jay's Electro Mecha (71740). With an adjustable mecha, ninja car, spider and a golden sword stand, they will experience hours of exciting ninja adventures. These cool ninja toys are specially designed to give little builders ages 4 and up a great play experience. Inside the box, they will find a complete model and a buildable character in each bag so they can get started quickly. There is also a Starter Brick - a partially built base to make building easier.
