- Littlefoot and his friends have faced The Joker before in the first season of Littlefoot's Adventures of Batman: The Animated Series, Pooh's Adventures of Rock and Rule, and other films before this one.
- This is the first Land Before Time crossover film to guest star Doc (aka The Lone Dinosaur) from The Land Before Time VI: The Secret of Saurus Rock and the reason why Doc guest stars in this film is because both Doc and Batman are real-live heroes.
- Scooby-Doo and Shaggy have faced the Joker before in the first episode of Pooh's Adventures of 101 Dalmatians: The Series and then with Fred, Daphne, and Velma in Winnie the Pooh and The Halloween Tree.
- This film will explain how Scooby-Doo and his friends met Batman since two episodes of The New Scooby-Doo Movies show Scooby-Doo and the gang recognizing Batman and Robin, which is why this film takes place before those two episodes.
- Jesse and Randolph have faced The Joker before in Pooh's Adventures of Free Willy and Pooh's Adventures of Free Willy: Yuletide and Red Tide and again with Elvis and Nadine in Pooh's Adventures of Free Willy 2: The Adventure Home.
- Like Daniel Esposito's film Pooh's Adventures of Batman: Mask of the Phantasm, this is an NTSC film with NTSC bits from The Land Before Time films, South Park: Bigger, Longer & Uncut, The Black Cauldron, Free Willy 1-3, The Goonies, The Nightmare Before Christmas, the Scooby-Doo films, the Balto films, An American Tail 1 and 2, 101 Dalmatians 1 and 2, We're Back!

- Free Willy, We're Back! A Dinosaur's Story, The Nightmare Before Christmas, and Batman: Mask of the Phantasm were released in theaters in 1993.
- Both The Nightmare Before Christmas and Batman: Mask of the Phantasm were first released on home video in 1994, the same year that The Land Before Time II: The Great Valley Adventure was released straight to video and both The Lion King and The Swan Princess were released in theaters.
- Aladdin, Princess Jasmine, Abu, Iago, and Genie will face Joker again in Pooh's Adventures of Aladdin and the King of Thieves.
