Doraemon: Boku, Momotarou no Nanna no sa

Nobita is trying to prove that the Monkey King exists so they went back to the time Sanzo began his pilgrimage. Doraemon used a virtual video game console and let Nobita play "Journey to The West" to give Nobita clothes that the Monkey King wears. Nobita messed up on prooving Monkey king exists. When Nobita and his friends played "Journey to The West" and they finished the game without fighting any demons. Later, they found out their world is ruled by demons. The problem is that Doraemon left the game console open in the past without closing it and demons started to appear to invade the world. Doraemon and the others now have to go back into the past to vanquish the demons.

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?

Nobita has been having a weird dream about a boy named Roppel and his strange companion Chami traveling in space. By a twist of fate, he met them in person where it turns out that they are real and that they were being pursued in space, causing their space vehicle to malfunction, connecting the space vehicle itself with Nobita's room. They journeyed to Roppel's planet and amidst their enjoyment, Nobita and Doraemon pledged to help Roppel's planet free from their oppressors.

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.
