Taking an Arrow to School

Dad forgets an important document at home. Dad calls Doraemon and asks him to bring it to him. Doraemon immediately uses the purple arrow to fly to Dad's company and hands the document to Dad. Then he returns home smoothly (because he has given the purple mate to Dad beforehand). Nobita has an idea after seeing the gadget. The next morning, Gian and Suneo are late. When they run to school, they find Nobita brushing his teeth in the yard. They see that Nobita, who love being late the most, is still so unhurried, so they slow down. After Nobita finishes his meal, he runs upstairs while saying that he is going to school. On the roof, Doraemon uses the gadget to move the arrow. After he shoots the yellow arrow, the arrow takes Nobita to school. When Gian and Suneo arrive at school slowly, the class has already started, and Nobita is sitting in his seat. Suneo and Gian are going to settle accounts with him after school. After school, Nobita is invited to Shizuka's house, so he goes directly to Shizuka's house with a blue arrow. Gian and Suneo miss. At Shizuka's house, Nobita sees a badminton racket and suggests playing in the empty lot, so they go to play with the green arrow. Gian and Suneo are originally planning to chase Nobita, but later Suneo thinks of using dorayaki to buy Doraemon and successfully got the gadget (the color of the target is green, purple, black and black). Just then, Nobita and Shizuka use the green arrow to go to the empty lot, and Suneo's mother happens to pass by Suneo and Gian. Suneo hands the black target to his mother, and at this time a dog takes the green target in the empty lot away. Gian and Suneo come over and snatch the arrow. They use green arrow, but the green mate is thrown into the ditch by the puppy, and they fall into it. Later, they use black arrow. At that time, Suneo's mother is grilling meat and stewing pot, and she actually uses the black mate as a pot mat to cool off. When the two fly to Suneo's house, they are immediately surprised to see the pot on the target. Later, Suneo's mother finds that she forgets to add ingredients to the pot and takes it away. The two arrive just in time and fall. After Nobita returns home safely, Doraemon is eating dorayaki and answering the phone. It turns out that his father forgets to leave important documents at home. Doraemon later finds extra purple arrow and lends them to Gian and the others. Nobita gives his purple arrow and bows to Doraemon. In addition, Gian is unwilling to admit defeat and uses purple arrow (Suneo also goes with him). Nobita learns from his mother that his father is going to Kyoto on a business trip and is taking the train to Nagoya (the purple mate is also inside). Gian and Suneo fly to dusk and feel something is wrong. They start to panic when they are about to crash into the train. Gian takes off his shirt to stop the arrow but fails. Doraemon happens to fly over and hits the two of them (the documents and clothes are still on the arrow). The three fall under the bridge and Doraemon quickly uses the "Guardian Paper" to save his life. In Nagoya, the two arrows reaches their destination. After Dad successfully gets the documents, he sees Gian's clothes but is confused.
