Aladar's Adventures of The Secret of NIMH is the fourth upcoming Dinosaur/Don Bluth film which is planned to be re-edited by Yru17. It will appear on Vimeo in the near future.
Aladar and his family (along with Fievel, Kermit, and their friends) went on a journey to meet Mrs. Brisby, who lost her husband and had kids. On this adventure in the Rose Bush, they meet Justin, who tells Mrs. Brisby about NIMH coming to the farm, and face to face with evil Jenner, whom Cat R. Waul and the Bowser family work for, to rescue Mrs. Brisby's family.
