- Like BowserMovies1989's film Pooh's Adventures of Teenage Mutant Ninja Turtles, this is an NTSC film with NTSC bits from The Land Before Time movies, The SpongeBob SquarePants Movie, The Lion King trilogy, South Park: Bigger, Longer & Uncut, Madagascar, Madagascar: Escape 2 Africa, Tarzan, The Princess and the Frog, The Black Cauldron, the Aladdin trilogy, the Scooby-Doo movies, Rock-a-Doodle, The Jungle Book 1 and 2, Mulan, The Swan Princess trilogy, Pinocchio, Mickey's Christmas Carol, Mickey, Donald, Goofy: The Three Musketeers, The Goonies, the Pokémon movies, We're Back!

- The reason why Jessie, James, and Meowth of Team Rocket are in this film is because Ash and Pikachu are the only Pokemon characters guest starring in Pooh's Adventures of Teenage Mutant Ninja Turtles.
- Teenage Mutant Ninja Turtles was released in theaters in 1990, the same year that Universal Pictures (the studio that released The Land Before Time movies) celebrated its 75th Anniversery in movie making and All Dogs Go to Heaven was first released on Home Video.
