On the Ninjago holiday: Day of the Departed, the ninja remeber those who have departed. Jay visits his parents at the junkyard; Lloyd and Misako remember Garmadon in the Corridor of Elders; Zane remembers his father in Birchwood Forest and Kai and Nya remember their parents too. Cole, unable to fully accept being a ghost, visits Sensei Yang as he begins to fade from existence, but accidentally releases the spirits of the ninjas' past enemies, resulting in an epic fight.
