Dungeon Party! (flashback)
When the Lowly come back with the Skull of Hazza D'ur, Vangelis tells them about all the power they can have with the skull. However, the Lowly insist the skull must be destroyed due to its evil powers. Vangelis realizes the Lowly know about the secrets and presses a button, causing the Lowly to fall through a trapdoor and into Rock-Bottom.
The Ninja head inside the Shintaro Palace where they are greeted by King Vangelis and Princess Vania.
During the night, a purple creature sneaks into Cole's bedroom and accidentally scares Cole. The Earth Ninja tackles the purple creature and a necklace pops out. Cole realizes the necklace belongs to his mother, but he has little time to think about it because the purple creature grabs it back and flees.
Cole alerts the rest of the Ninja about everything he witnessed, but they all think Cole is dreaming and tell him to head back to sleep. As Cole trots back to his bedroom, Vania sneaks up on Cole and tells him that she believes in what he saw. The two then head out of the palace so Vania could show Cole where the purple creature came from.
They warn King Vangelis, but he is very disappointed in Vania for putting a visitor in danger. He promises to send his guards to retrieve Cole, but the Ninja also want to help. Vangelis forbids them from entering the mines, but after their conversation with the king, they enter anyways.
Wu is enjoying a cup of tea in the gardens when he spots Cole and Vania coming out of the mines. Cole tells Wu everything he saw so they head to Vangelis to warn him. However, he reveals himself to be the Skull Sorcerer and releases the trap door, causing Cole and Wu to fall. Vania decides to go after them despite the threats made by Vangelis.
Vangelis orders his guards to lock up Chompy in order to cover up what truly happened with Vania.
The Upply, Cole, Wu, and Vania make it back to the top. They head to the Throne Room and free Chompy, but Hailmar and the Winged Guards of Shintaro enter and demand Cole's arrest. Fighting takes place and Chompy turns into a huge dragon allowing Cole and the Upply to flee the scene. Vania tries to convince Hailmar that Vangelis is wrong, but Hailmar charges at Vania.
Everyone gathers at the Shintaro Palace to watch Vania become the queen of Shintaro. She promises peace and equality for all living above and below. They then watch the Ninja leave the Kingdom of Shintaro.
