- This is one of a few Land Before Time/Scooby-Doo crossover films to guest star Tennessee Tuxedo and Chumley, since they didn't guest star in LionKingRulezAgain1's film Pooh, Simba, Timon, and Pumbaa's Adventures of Scooby-Doo 2: Monsters Unleashed. This is because LionKingRulezAgain1 doesn't have the footage of the Tennessee Tuxedo cartoons.
- Unlike LionKingRulezAgain1's film Pooh, Simba, Timon, and Pumbaa's Adventures of Scooby-Doo 2: Monsters Unleashed, this is an NTSC film with NTSC bits from The Land Before Time movies, Dumbo, Thumbelina, The Swan Princess movies, The NeverEnding Story movies, A Troll in Central Park, South Park: Bigger, Longer & Uncut, Free Willy 1-3, The Goonies, The Nightmare Before Christmas, The Black Cauldron, The Princess and the Frog, Aladdin movies, The Little Mermaid movies, The Jungle Book 1 and 2, Talespin: Plunder and Lightning, Pinocchio, The Lion King movies, Mickey, Donald, Goofy: The Three Musketeers, Mickey's House of Villains, A Goofy Movie, An Extremely Goofy Movie, The Prince and the Pauper, Mickey's Christmas Carol, Madagascar, Madagascar: Escape 2 Africa, Madagascar 3: Europe's Most Wanted, Quest for Camelot, Ponyo, We're Back!
