Ep 2. The Jade Princess

As the episode begins, the Ninja are still searching for their missing teammate Zane. They discover that he has been taken by the Sons of Garmadon, a dangerous criminal organization seeking to resurrect their leader, Lord Garmadon.

In order to rescue Zane, the Ninja must obtain the only remaining Oni Mask, which is in the possession of the Jade Princess. The Princess has been cursed by the mask and turned into a giant serpent, making it difficult for the Ninja to approach her.

Jay comes up with a plan to distract the serpent while the others sneak in to retrieve the mask. With the help of their new ally, Princess Harumi, they manage to retrieve the mask and save Zane.

However, their victory is short-lived as they learn that the Sons of Garmadon have acquired three of the four Oni Masks and are on their way to resurrect Lord Garmadon. The Ninja now face their greatest challenge yet as they must stop the Sons of Garmadon and prevent the return of Lord Garmadon.
