Doraemon: Nobita's the Night Before a Wedding

Nobita's dad stumbled upon a strange advertisement of a fantastic resort on television at midnight. Sleepy as he was, he made a reservation even though he didn't even realize he was talking to the advertisement. The next day he discussed with the family their holiday plans, only to realize he could not find the place anywhere on earth. All of a sudden though, there was a suitcase in Nobita's room and intrigued as he was, he opened it only to find a portal to a beautiful resort managed by tin robots. Better still, it's absolutely free. However, it seems that there is a hidden agenda behind the person who invites them there.

After Suneo bragged about having a ranch, Nobita was asked whether or not he has one, pressuring him to say yes. Doraemon won a number of lotteries for useless planets in the belt between Mars and Jupiter. When Suneo and the rest came to see the ranch, Nobita happened to read the last of the lottery number to the go-anywhere-door, leading them to a huge dreamlike area. As Nobita's toy horse pranced around because of the wind-up life gadget, Suneo and the others became interested in doing the same to their toys and let them live in the area. So they decided to make their own clockwork city.

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.

Doraemon and Nobita were using special shoes that allows them to jump into the worlds of the books that they want. Nobita let Shizuka use those shoes to enter the world of the book that she wants. Shizuka got lost in one Nobita's Sinbad Legend of the Seven Seas book. After Nobita's mother burned all of his books, Doraemon and the others must find another way to save Shizuka.
