LEGO Ninjago: Masters of Spinjitzu: Rebooted Season 4 (DVD)
Loss is a powerful thing. The loss of Zane in the battle against the Overlord has fractured and disassembled our favorite Ninja team. But when they receive a mysterious invitation to an unrecorded island for Master Chens Tournament of Elements, they get wind that their friend could still be alive, and in order to get him back, theyll not only have to face others gifted with unique elemental powers, but eventually battle each other.
