Littlefoot's Adventures of Dumbo 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 SpongeBob, Stan, and their friends) travel to the circus and board the circus train, Casey Jr. While onboard they realize that one of the elephants was expecting and met Dumbo, a young elephant with large, floppy ears. While the other elephants ridicule him, Littlefoot and the gang don't laugh at him because they think that they look good on him. Later, when his mother was imprisioned, they met Timothy Q. Mouse and they realized that he could use his large, flappy ears to take flight and he became the star of the circus and his mother was let out and they share a private coach at the rear of the train. After that, Mr. Thicknose decided to join Littlefoot and his friends on their adventures.

- Dumbo and Timothy Q. Mouse were originally planned to join Littlefoot's adventure team in later adventures after this film, but Yru17 found out that Timothy Q. Mouse has already been taken by CoolZDane for his Danny's Adventures films, so he decided to replace them with Mr. Thicknose instead, which means Mr. Thicknose will join Littlefoot and his friends after this film. However, Dumbo and Timothy Q. Mouse will guest star in some Land Before Time crossovers alongside Jim Crow and his Brothers.
