Lost Item Return Spray

Nobita screams in horror when he notices that all of his favorite books are missing. He runs to the storage room where Tamako usually hides them, but he can't find them there either. Nobita runs to his mother to complain about the problem, and she, who was writing in her personal book, explains that he shouldn't waste his time on nonsense and sends him upstairs. In his room, Nobita complains to Doraemon about the loss of his book and asks him to help him somehow. At first, Doraemon distances himself from Nobita, feigning a refusal to help him, and when the latter begins to cry, he consoles him and suddenly all of the lost books return to Nobita, which makes him very happy. Doraemon shows him the Lost Item Return Spray and lets Nobita try it. He throws a baseball out the window and hits Gian on the head. Then, the ball returns when Nobita uses the spray. He starts spraying his entire room to get back all his lost things. When Nobita decides to try it on Doraemon, he refuses and starts running away from him. Nobita, chasing Doraemon, accidentally falls into his mother's bag. Tamako asks Nobita to help, but he refuses and sticks out his tongue, accusing her of throwing away his favorite books. Enraged, Tamako forcibly sits Nobita down and starts scolding him until she gets tired. After catching her breath, she leaves the house to run errands, and Nobita decides to visit Shizuka. When he reaches her house, he also meets Suneo, who invites her to his house. Nobita, reluctantly, also goes to him. When they reach the Honekawa house, Suneo turns on a video tape on the TV and he, along with Shizuka and Nobita, watches how he and his relatives were having fun outdoors. After watching Suneo's tape to the end, Nobita flies to the clearing and notices a lot of trash that has accumulated after the Honekawa family's fun. He sprays the entire clearing with the spray, and the trash flies away. Returning to the city, Nobita meets Doraemon and Tamako, who has lost her personal belongings and is very upset. Nobita suggests going home and finds his wallets at Tamako's doorstep, which makes her very happy. He explains to Doraemon that he accidentally sprayed his mother's bag when he was chasing it. Tamako continues to rejoice at her found personal belongings, and Doraemon and Nobita smile at each other.

Meanwhile, Suneo is laughing while reading a comic book and hears some noise from the street. He looks out the window, and a banana peel hits his face, followed by a lot of trash, forming a huge garbage mountain near the window, causing Suneo to get scared. His mother, seeing this, begins to scold him. Suneo tries to justify himself and, feeling offended, begins to cry.
