Littlefoot in Fantasmic! (Tokyo Disney Sea) 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.
The magic, illusions, and the adventure of Fantasmic returns when Littlefoot, Ash Ketchum, Stan, Mikey, Jesse, and their old and new friends reunite once again with Mickey Mouse to celebrate the debut of all-new Fantasmic adventure at Tokyo Disneyland's Tokyo DisneySea park in Urayasu, Chiba, Japan. But the Team Rocket team up with all the villains from our heroes' past (who were sent by the evil Bowser Koopa), the nightmare is back. Now it's up to Littlefoot and the rest to stand tall against evil once again, restore the imagination, and stop the Team Rocket and the villains plots using the elements of water, light, and fire.
