"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?
A new enemy rises and the battle is joined! When the evil Lord Garmadon unleashes an army of stone warriors on the world of Ninjago, the ninja find that not even they can stop this new menace!
"Jay, Cole, Zane, Kai, and Sensei Wu are strangers in an even stranger land-- Garmadon City! But the name is not what's strange! The fact that everything is made of stone-- the streets, the buildings, the trees, even the people!-- that's the really strange part. But how do you save people who have been turned into stone who don't want to be saved, and will do anything to stop you?.
Under the leadership of Sensei Wu, the Masters of Spinjitzu, joined by a contrite Lord Garmadon and his son Lloyd, travel throughout the world to dismantle the doomsday devices that were set up by Garmadon and timed to activate in the event of his defeat.
