A year after Raimundo has been promoted to leader of the Xiaolin Dragons, no Shen Gong Wu has revealed itself. But one day, 'The Celestial Horn' activates and uses itself; causing the mane six to be transported to the world of Xiaolin Showdown. They become Xiaolin Dragons in-training and help the Wudai Warriors to collect the Shen Gong Wu and further stop the Heylin order from reigning. A new quest is then unfolded to search for the 'Heylin Wu' created by Wuya before her fight with Master Dashi; only the Heylin can unleash the true power of these evil Shen Gong Wu. The two types of Shen Gong Wu have started to activate because of a curse that the Xiaolin Warriors must get to the bottom of. Just to clarify; ponies are ponies, humans are humans.
