The Dora Dora Space-time Adventure: The Mystery of Nobita's Figurines

After Nobita comes home from school, he sees Doraemon tidying up the house in an apron. Doraemon says that Nobita's mother asks him for help. He is afraid that the 4D Pocket will be dirty, so he takes it down first, and takes out the "Secret Garbage Disposal Hole", and throws unwanted things such as waste into it. . As a result, he accidentally throws away Nobita's clay work at school as garbage!

In order to pick up the clay work, Doraemon ties rope to the pillars under the corridor and rappells into the different-dimensional space of the secret garbage disposal tray. Unfortunately, Nobita comes to take out the trash and hits Doraemon, causing his rope to fall off...! Doraemon keeps falling down like this, but the exit turns out to be the Jomon era! It turns out that this secret garbage disposal tray will throw garbage into ancient times, and it is a kind of time machine.

Doraemon is chased by a big eagle, and as a result, he is farther and farther away from the gadget exit. However, his pocket is not there.

After that, Gian, Suneo and others throw quilts, bicycles and other unused things into this hole.

After Doraemon falls to Japan in the Jomon period, it is soon discovered by primitive people. He is surprised to find that the clothes and bows and arrows used by primitive people are actually the garbage that Nobita asks some people to throw away.

The next morning, Doraemon goes to the tribe of the primitive people and sees that the primitive people are using the things that are thrown away by those people. Unexpectedly, Doraemon and the two primitive people he met before meet again. As a result, Doraemon chooses to leave again.

In the evening, Doraemon takes the clay work away, just as Nobita is called by his mother to eat, but he can't not see the shadow of Doraemon. Nobita curiously fiddles with the rope on the "Secret Garbage Disposal Hole", wondering what's going on.

Doraemon finally takes the clay work and leaves, but sees the primitive people are very curious about the bicycle that falls from the sky.

When primitive people finally see quilts, TV set and other items falling from the sky, they unexpectedly sees Nobita also fall.

Nobita finally comes to that era, just happens to see Doraemon, followed by Nobita's 0-mark test. Nobita and Doraemon finally meet again, only to be attacked by a big eagle. After the eagle captures a little girl in the primitive man, in this extremely critical situation, Doraemon instructs the primitive man to use the existing items to save the little girl. Doraemon sits on a kite made of 0-mark test papers, shoots down an eagle with a slingshot, and catches the girl with a quilt with Nobita.

After the girl is rescued, Nobita finally gets back the broken clay work, and the girl makes Nobita and Doraemon's figuribes for Nobita. Nobita combines the head of the doll with the clay work and gives it to the girl.

Nobita and the others go back with great difficulty, and as a result, archaeologist discovers the figurine made by Nobita.
