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 and the now-defunct Mickey's Toontown Fair.
After a pair of witches walk by pushing a float bearing the parade's logo, several characters dance down the street in pairs (many of them wearing masks), including Snow White & Dopey, Pinocchio & Geppetto, Alice & the Mad Hatter, Tweedle Dee & Tweedle Dum and Aladdin & Jasmine. 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).
Next, we see Winnie the Pooh, Tigger, Eeyore, Piglet and Christopher Robin dancing down the streets. Behind them is Pooh's house, carrying Rabbit and Kanga & Roo. Like Mickey and his pals, Pooh and his friends are all dressed up in Halloween costumes.
This unit is themed to Adventureland, featuring many of Disney's pirate characters.
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
Horace Horsecollar, Clarabelle Cow and several rope-twirling cowboys open this Frontierland-themed unit. Behind them, a silo float carrying Country Bears Wendell, Shaker, Liver Lips and Big Al rolls by.
This unit is themed to the Disney Villains.
First, we see a pumpkin-headed man rolling by on a lighted ball, followed by a float carrying an all-skeleton rock band. Behind them, Pain and Panic dance in cages while waving glowsticks.
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, Jafar, The Sheriff of Nottingham, The Queen of Hearts, Frollo and Foulfellow. A float behind them, featuring Chernabog, carries additional villains, including Maleficent, Dr. Facilier and The Queen.
Shenzi, Banzai and Ed trail behind, closing out this unit.
Goofy's Trick-or-Treat Candy Hop
The finale of the parade, themed around Halloween candy and promoting Goofy's Candy Co. A group of cheerleaders twirl banners and many candy helpers pass by, giving out candy to spectators along the parade route.
Following the contraption are two Cast Members carrying a banner with the words "The End" written on it.
