Personally, I am not really familiar with the LEGO Ninjago series, but just to give a brief background, the LEGO Ninjago series was introduced in 2011 around four Ninjas: Kai, Cole, Jay and Zane. They have been trained by their master Sensei Wu to fight forces of evil to protect the land of Ninjago.
This summer, LEGO released 9 new LEGO Ninjago sets and a new LEGO Ninjago product called the LEGO Ninjago Airjitzu Flyer.
