Dorami-chan: Mini-Dora SOS

At the graduation day in Robot School, mysterious flow pulls in all of Dorami's friends and classmates, including Doraemon. Doraemons coming to the rescue, trying to solve this mystery and reveal one who stay behind all of this.

Nobi Nobita is a 4th-grade boy in Tokyo. One day, a round, blue cat-style robot (minus ears) pops up in his desk drawer. Nobita's great-great-grandson (or something) lives in the 22nd Century, but thanks to Nobita's mistakes, the entire family is living in poverty. To rectify this, Nobita's descendent is sent Doraemon back to the past, to help prevent Nobita from making mistakes. Of course this is a difficult task since Nobita is the weakest and least intelligent child in his class. Doraemon does, however, have a 4-dimensional pocket on his front, which contains cool gadgets from the future. With these toys, Doraemon will try to help Nobita. Unfortunately, Nobita also has the bad habit of misusing Doraemon's gadgets and landing himself in yet more trouble?

The movie is sort of a prequel to the entire series, it showed the life of Doraemon before traveling to the 20th century: How he was made, how he was partially broken, how he lost his ears, how he met the Nobi family and decides to return to the past to help Nobita.

One day Nobita found a small sapling behind the hill but his mom won't allow him to plant it in the backyard. Using Doraemon's special tool, they made the tree alive so it could move around freely. Nobita name it Ki-bō and the two became like brothers. From there, a new adventure awaits...
