Isaimini is a popular online platform that provides free access to Tamil dubbed movies, including Hollywood films. However, I must emphasize that downloading copyrighted content without permission is illegal and can result in severe consequences.

I'm assuming you're referring to the 2019 Disney movie "Dumbo" and looking for information on how to download it in Tamil from Isaimini.

"Dumbo" is a 2019 American fantasy film directed by Tim Burton, with a screenplay by Ehren Kruger. The movie is a remake of the 1941 Disney animated film of the same name. The story follows a young elephant named Dumbo, who is born with oversized ears and is ostracized by his peers. However, he discovers that his unusual ears give him the ability to fly.
