The sinister forces of Skulkin threaten the harmony of the planet, and it will take a fearless army of skilled Spinjitzu ninjas to quell their evil plot. But beware — your deadly enemies will stop at nothing to get in your way. Can you and your fellow Hero troops beat these rogue warriors at their own game? Or will you succumb to their alluring power and join the forces of evil?
