Littlefoot's Adventures of Mad Scientist is another upcoming new Land Before Time crossover film planned to be re-edited by Yru17. It's unknown if the film will be shown on YouTube.


  • SpongeBob SquarePants, Patrick Star, Sandy Cheeks, Squidward Tentacles, and Eugene Krabs guest star in this film.
  • This is an NTSC film with NTSC bits from The Land Before Time films and The SpongeBob SquarePants Movie.
  • Littlefoot and his friends were originally planned to guest star in Pooh's Adventures of Mad Scientist and Yru17 originally planned to do a SpongeBob SquarePants crossover with the film, but they were cut out of the film and replaced with Toaster and his friends for some reason. So Yru17 ended up doing a Land Before Time crossover with this film with the SpongeBob SquarePants characters as guest stars.
