Littlefoot's Adventures of Pokémon: The First Movie is the first feature-length Land Before Time/Pokémon crossover film planned to be re-edited by Yru17. It will appear on Vimeo after Littlefoot's Adventures of The Lion King is released on YouTube.
- SpongeBob SquarePants, Patrick Star, Squidward Tentacles, Sandy Cheeks, Eugene Krabs, Stan Marsh, Kyle Broflovski, Eric Cartman, Kenny McCormick, and Sheldon J. Plankton guest star in this film.
- Plankton will team up with Jessie, James, and Meowth of Team Rocket in this film.
- This film explains how Stan and the gang meet Ash and the gang. Winnie the Pooh Goes to South Park: Bigger, Longer & Uncut was originally planned to explain how Ash and his friends meet Stan and his friends, but that film and Pooh's Adventures of Stand by Me ended up taking place after both versions of Winnie The Pooh In Fantasmic! and Pooh's Adventures of Turtles Forever because that film marked the first time Misty, Togepi, and Brock faced The Shredder, Yru17 wanted to use Darby and Buster for the Winnie the Pooh/Land Before Time sequels starting with Pooh's Adventures of The Land Before Time II: The Great Valley Adventure, and he didn't want the audience to get confused a bit, so this film ended up explaining how Stan and the gang meet Ash and the gang.
- Like BowserMovies1989's film Pooh's Adventures of Pokémon: The First Movie, this is an NTSC film with NTSC bits from The Land Before Time films, The SpongeBob SquarePants Movie, and South Park: Bigger, Longer & Uncut.
