The parade is comprised of several themed units, many of them themed to the Magic Kingdom's themed lands:
Mickey's Trick-or-Treat Bash
This is the opening unit, which is themed heavily to Fantasyland.
After a pair of cast members walk by pushing a float bearing the parade's logo, several characters dance down the street (many of them wearing masks), including Snow White, Dopey, Pinocchio, Geppetto, Alice, the Mad Hatter, Tweedle Dee and Tweedle Dum, Aladdin with Jasmine, Pluto, Winnie the Pooh, Tigger, Eeyore, and Piglet. Behind them is a gazebo, carrying Mickey Mouse, Minnie Mouse, Donald Duck and Daisy Duck dressed in Halloween costumes (Mickey as a jester, Minnie as a witch, Donald as a knight and Daisy as a princess).
This unit is themed to Adventureland, featuring many of Disney's pirate characters.
Peter Pan, Wendy and the Lost Boys ride on a pirate ship carrying Captain Hook, Mr. Smee and their Crew. A flag unit from the defunct "Pirate and Princess Palooza" follows. Next, Captain Barbossa and several pairs of pirates and wenches dance as a pirate rock carries Jack Sparrow, Angelica and several skeletal pirates.
Haunted Mansion Cemetery Soiree
Themed to Liberty Square's Haunted Mansion attraction, several of its Happy Haunts make appearances.
The unit begins with the graveyard caretaker and his dog. An army of ghoulish gravediggers dance while carrying shovels and banging and scraping them on the street, which causes sparks to fly. A hill with several tombstones rolls by.
Next, several of the ballroom dancers waltz into view, followed by a float carrying the Hitchhiking Ghosts.
Halloween Hooten-Nanny Hoedown
Trick-or-Treat Candy Hop
The unit, themed around Halloween candy, begins with Wreck-It Ralph characters Vanellope von Schweetz, followed by the titular character of the 2012 movie on a large "Sugar Rush Candies" truck. Three large candy corn pieces (re-purposed from the now-defunct "Pixar Countdown to Fun!" parade at Hollywood Studios) come not too far behind. Goofy himself is in the parade while riding on a giant candy-making contraption.
The finale unit is themed to the Disney Villains.
A large group of villains dance down the street, singing "It's Good to Be Bad". Among the villains are the Big Bad Wolf, Cruella de Vil, The Sheriff of Nottingham, The Queen of Hearts, Bowler Hat Guy, Frollo, Dr. Facilier, J. Worthington Foulfellow, Stromboli, the The Evil Queen, Captain Hook, Oogie Boogie, Anastasia Tremaine and Drizella Tremaine. A float behind them, featuring Chernabog, carrying additional villains, including Maleficent, Jafar and Ursula.
Following the contraption are two Cast Members carrying a banner with the words "The End" written on it.
