Codename: Arcturus

Codename: Arcturus is the sixth episode of the third season of LEGO Ninjago: Masters of Spinjitzu.

Plot
In the ocean's depths, Pythor leads the Nindroids in attaching balloons to the Overlord's preserved body, allowing them to raise the Nindroid MechDragon. With their leader secure, Pythor, General Cryptor, and the Nindroids take off towards The Lost City of Ouroboros.

At The Temple of Light, Lloyd gives up his Golden Power to restore the Ninjas' elemental powers. Meanwhile, at Borg Tower, Sensei Wu spots General Cryptor aboard a train heading for Ouroborus. He tries to send Jay and Cole to investigate, but they are fighting over Nya once more at the movie theater. Wu sends Kai instead, but the Red Ninja has become overconfident with the heroes' previous victory over the Overlord. As a result, he is attacked by Nindroids, and Pythor himself grabs him, tapes his mouth, and takes him prisoner.

Cole, Jay, Zane, and Lloyd discover the secret of Arcturus and head for Ouroboros. When they arrive, the floor opens, revealing the OverBorg's ultimate creation, Codename: Arcturus - a rocket designed to reach Arcturus, the star that contains the lost Golden Weapons.

The Ninja secretly release Kai and board the rocket, preparing to go somewhere they never expected: space!
