When Lord Garmadon finds himself on the Dark Island, the Overlord leads Garmadon through the thick jungle where they find a large boulder with four hand dials. Using his four arms, Garmadon turned the dials, causing the entire island to rise from the sea.
The Ninja set up their base near Jankikai Jungle and try to avoid detection from the Stone Army. While the Ninja (except Lloyd) head out to find the Temple of Light, Wu fetches water from a stream. However, he is spotted by a Stone Warrior and two Stone Swordsmen. Luckily, Lloyd and Misako come to rescue Wu.
The Ninja begin running towards the base and inform the team they were spotted. Since they were able to find the Temple of Light, they hop into the Earth Driller and being making their way to the temple.
Kai, Jay, Cole, Zane, Misako, and Nya use the Earth Driller to get away from the Stone Army Mech. However, they are caught from behind, but Lloyd uses his Elemental Powers to destroy the mech. This sets up a potential fight where Lloyd has the change to defeat his father, but he becomes nervous and doesn't fight him. When reinforcements arrive, they drill to the Celestial Clock.
Later, Garmadon, who is still in the jungle, asks about the sound from the Celestial Clock, and the Overlord tells him that the countdown is complete. He soon sees a yellow beam towards his camp which is creating the Garmatron.
The Ninja, Wu, and Misako follow the tracks of the Garmatron, but run into trouble when they face a corrupted Nya. The Ninja fight her while Lloyd, Wu, and Misako continue. Eventually, the Ninja defeat her and meet up with Lloyd.
