LEGO Ninjago. Masters of Spinjitzu

"Sensei Wu has trained Cole, Zane, Jay, and Kai to be Masters of Spinjitzu, and together they defend the world of Ninjago from the dark forces of the Underworld. But when Samukai boasts that he can defeat Sens[e]i Wu and his four young ninja, Garmadon takes him up on his bet!" -- P. [4] of cover.

Cole, Zane, Jay, and Kai try to defeat a foe who can control the mind. One of them actually does fall under the spell of the Hypnobrai and the question for the rest is how will the fellow ninja react?

After flying through an electrical storm, ninja Jay crash-lands in an alternate world where Sensei Wu never taught the ninjas the art of spinjitzu and the Serpentine rule with skeleton warriors as their servants.
