Master Xandred is upset about Halloween. Octoroo has a plan that involves Trickster, a Nighlok that traps the Rangers in bad dreams. In a forest, the Moogers attack people in animal costumes. Trickster watches the scenes from a movie theatre laughing. The Rangers (also dressed in animal costumes) arrive to the scene. After a brief roll call, the Rangers fight the Moogers. After the battle, Blue Ranger enjoys his best costume but then the Rangers ponder how they got to the forest. The Rangers are then teleported to a concert where Mia sings and the Rangers are her background dancers. After this, Trickster prepares their next dream. The Rangers are de-morphed and teleported in a quarry where they fight against Moogers. After briefly pausing and rewinding the events, Trickster enters the scene and challenges the Rangers. After a lengthy morph sequence (which Trickster points out), the Rangers take on Trickster and the Moogers.
