- Ash Ketchum, Pikachu, Misty, Brock, Togepi, SpongeBob SquarePants, Patrick Star, Squidward Tentacles, Sandy Cheeks, Eugene Krabs, Simba, Nala, Timon, Pumbaa, Zazu, Stan Marsh, Kyle Broflovski, Eric Cartman, Kenny McCormick, Scooby-Doo, Shaggy Rogers, Fred Jones, Daphne Blake, Velma Dinkley, Alex, Marty, Melman, Gloria, The Penguins of Madagascar (Skipper, Kolwalski, Rico, and Private), King Julien, Maurice, Mort, Princess Tiana, Prince Naveen, Louis, Ray the Firefly, Mama Odie, Taran, Princess Eilonwy, Fflewddur Fflam, Gurgi, Orddu, Orgoch, and Orwen, Aladdin, Princess Jasmine, Abu, Genie, Iago, Sebastian, Baloo, Bagheera, King Louie, The Vultures (Buzzie, Flaps, Dizzy, and Ziggy), Jiminy Cricket, Jesse Greenwood, Elvis, Randolph Johnson, Nadine, Fu Dog, Kenai, Koda, Rutt and Tuke, Roger Rabbit, Ttark, Woody Woodpecker, Barney the Dinosaur, Baby Bop, BJ, Riff, Toaster, Lampy, Radio, Blanky, Kirby, Lumiere, Cogsworth, Mrs. Potts, Chip, Po the Panda, The Furious Five, Shifu, Devon and Cornwall, Chanticleer, Charlie Barkin, Itchy Itchiford, and Jack Skellington guest star in this film.
- Jean-Bob, Speed, Puffin, and Whizzer make their first debut in this film. This idea was because yru17 thought that it would be interesting if some of the characters from any of The Swan Princess films would visit a chocolate factory and meet Willy Wonka.
- This is one of Yru17's crossover films guest starring Tiana and Naveen as humans instead of frogs. Yru17 decided to guest star them as humans in some of his crossover films so he would not dissapoint RatiganRules, who plans to guest star Tiana and Naveen as humans in his films.
- The main reason why SpongeBob and his friends guest star in this film guest star in this film is because the plot for the SpongeBob SquarePants TV film Atlantis SquarePantis is similar to the plot for the 1971 film Willy Wonka & the Chocolate Factory and another reference to that film on SpongeBob SquarePants is in the episode The Card, in which there are only five talking Mermaid Man and Barnacle Boy trading cards in existance just like there only being five Golden Tickets in existance.
- Like Sonic and Amy in Willy Wonka & the Chocolate Factory and ToonJoey34's upcoming film Pooh's Adventures of Willy Wonka & the Chocolate Factory, this film will use the 1971 version starring Gene Wilder, not the 2005 Tim Burton remake version starring Johnny Depp, which an unregistered user named Ellen requested Yru17 to re-edit after (while Yru17 still believes that only one version is enough for a crossover film, accoriding to BrerJake90).
- The film will have Willy Wonka's flashback features Littlefoot Meets Peter Pan.
