Combining Glue

When Nobita is sitting in the room doing homework, he is hit on the head by a helicopter toy and suffers a severe pain. It turns out that Yamaguchi is playing underneath and accidentally flies over. After he apologizes to Nobita, at Nobita's request, Yamaguchi says that he will lend Nobita a ride once, but Nobita is playing with the helicopter in the empty lot and doesn't know where it falls. He can't find it (actually, it is secretly borrowed by a young man who passes by to play with). Yamaguchi cries anxiously and says that he will report to Nobita's mother. Nobita also becomes anxious. At this time, a strange man with a snake body suddenly appears. It turns out that Doraemon combines the snake with "Combining Glue". After hearing about Nobita, he combines it with the dog, smells the smell to find clues, and finally finds out that Suneo has taken it. Nobita and the others turn into turtle and fish and find a remote-controlled helicopter in the river. But when Nobita begs Suneo, Suneo says that Gian has snatched it away. When Nobita is feeling desperate, a sumo wrestler happens to come over, so Nobita combines with the sumo wrestler to find Gian. Gian can't beat him and has to return it to Nobita. Nobita returns it to Yamaguchi to solve the problem. After returning home, Nobita finds that it is too late to finish his homework, so he thinks of merging with Shizuka, so that his mind will be easier to work faster. However, because Shizuka is having dinner, he does his homework after merging, and Shizuka's body keeps wanting to go home.
