Littlefoot's Adventures of Mulan is another Land Before Time crossover film planned to be re-edited by yru17. It's unknown if the film will be shown on YouTube.
Littlefoot and his friends (along with Stan, Taran, Scooby-Doo, and their friends) take a time-traveling vacation to China and meet Mulan and help her join the army.
- Stan Marsh, Kyle Broflovski, Eric Cartman, Kenny McCormick, Taran, Princess Eilonwy, Fflewddur Fflam, Gurgi, Scooby-Doo, Shaggy Rogers, Fred Jones, Daphne Blake, Velma Dinkley, The Goonies (Mikey Walsh, Brand Walsh, Mouth Devereaux, Data Wang, Chunk Cohen, Andy Carmichael, Stef, and Sloth Fratelli), Jean-Bob, Speed, Puffin, Chanticleer, Celebi, Mickey Mouse, Donald Duck, Goofy, Bugs Bunny, Daffy Duck, Rex, Woog, Elsa, Dweeb, Jesse, Elvis, Randolph Johnson, Nadine, Charlie, Itchy, Jack Skellington, Zero, Oogie Boogie, Creeper, Carface, Killer, Lord Rothbart, The Grand Duke of Owls, and Team Rocket (Jessie, James, and Meowth) guest star in this film.
- Oogie Boogie, Creeper, Carface, Killer, Lord Rothbart, The Grand Duke of Owls, and Team Rocket (Jessie, James, and Meowth) will work for Shan Yu in this film.
- Genie was originally planned to guest star in this film, but Yru17 felt that Genie would be in Simba, Timon, and Pumbaa's Adventures of Mulan II, since Simba, Timon, and Pumbaa's Adventures of Mulan was the only Lion King/Mulan crossover film made before Genie became a member of the Jungle Adventure Crew, so Yru17 decided to cut the character out of the film.
- Like Disneydaniel93's film Pooh's Adventures of Mulan, this is an NTSC film with NTSC bits from The Land Before Time movies, South Park: Bigger, Longer & Uncut, The Black Cauldron, the Scooby-Doo movies, The Goonies, The Swan Princess trilogy, Rock-a-Doodle, the Pokémon movies, the Mickey Mouse films, the Looney Tunes films, We're Back! A Dinosaur's Story, Free Willy 1-3, the All Dogs Go to Heaven trilogy, The Nightmare Before Christmas, and Rock-a-Doodle.
- The only reason Jessie, James, and Meowth of Team Rocket guest star in this film is because Ash and Pikachu were the only Pokémon characters to guest star in Pooh's Adventures of Mulan.
- Like in Pooh's Adventures of Mulan, Littlefoot, Stan, and their friends see Jack Skellington and his ghost dog Zero joining the men after Mushu told Mulan and the others to be just like the men in camp and Littlefoot says "Jack Skellington? Is that you?" and Jack says "Littlefoot? Has it been while since I last saw you?" and the others were to see him.
- Mulan was released in theaters in 1998, the same year that both The Land Before Time VI: The Secret of Saurus Rock and Scooby-Doo on Zombie Island were released directly to video and The Black Cauldron was released on home video for the first time ever.
- This film actually takes place before Pooh's Adventures of Honey, I Shrunk the Kids, which explains Littlefoot and his friends already knowing Mushu.
