- Unlike LionKingRulezAgain1's film Simba, Timon, and Pumbaa's Adventures of Looney Tunes: Back in Action, this is an NTSC film with NTSC bits from The Land Before Time films, Pokemon South Park: Bigger, Longer & Uncut, Dinosaur, the Star Wars films, The Black Cauldron, The Goonies, We're Back! A Dinosaur's Story, Free Willy 1-3, The Dot of Nimh films The Muppets The Great Mouse Detective, Scooby Doo, A Bug's Life, and Tarzan, and more.
- This is one of a few films in which the witches from The Black Cauldron have ever guest starred without Genie (the Flyng Dutchman takes over Genie's role in a few other Littlefoot's Adventures films in which the witches appear without Genie). In other Littlefoot's Adventures film guest starring a few characters from The Black Cauldron, but not Genie from Aladdin or SpongeBob and the gang, Taran, Princess Eilonwy, Fflewddur Fflam, and Gurgi are seen guest starring without the witches just like in a few Shin Chan's Adventures films guest starring these characters because they might do fine without the witches.

- Scooby-Doo and Shaggy make a full guest appearance with Fred, Daphne, and Velma in this film, despite their cameos in the real film.
- The only reason Celebi, Mewtwo, and Team Rocket guest star in this film is because Ash Ketchum, Pikachu, Misty, Togepi, and Brock are the only Pokémon characters guest starring in Pooh's Adventures of Looney Tunes: Back in Action.
