Locker Cutter

Tamako instructs Nobita to clear the room of manga, which he reluctantly agrees to and begins. Then he notices Doraemon, who enters the room and pulls out dorayaki from the closet door, which surprises Nobita and asks why. Doraemon shows him a locker cutter, which can be used to cut holes in different walls and floors and lock things in them so that nothing happens to them. With this locker cutter, Doraemon cuts a large rectangle on the floor and there becomes a storage room, where Nobita puts a whole stack of manga. Nobita decides to try this gadget. He makes a small rectangular space in the window, in which he puts his test with 0 points, so that Tamako will not find anything. He runs downstairs, where he runs into Tamako, who tells him to take out the trash and leaves. Then Nobita makes a hole in space with the help of the locker cutter and throws all the trash in there, which makes Doraemon very angry, and Nobita then puts a trash can on his head and runs out of the house, and Doraemon starts chasing him until he finds out that Nobita is nowhere to be found. As soon as Doraemon leaves, Nobita climbs out of the space in the wall and thinks about what else not to try until Suneo's toy plane crashes into him. Nobita came up with an idea and decided to hide the plane in a hole in the asphalt, which was drawn by the locker cutter. As soon as Suneo runs up to Nobita and wonders where his remote-controlled toy plane flew off to, Nobita wriggles out of answering the question by hiding in another hole in space. Gian comes up to Suneo and asks what happened. While Suneo was talking, Nobita opened the hole and placed his toy airplane near Gian, to which he and Suneo are surprised that the toy appeared out of nowhere. As soon as Gian leaves, Nobita throws pebbles at him. Gian thinks that Suneo threw them and starts chasing him, and Nobita watches what is happening through the hole from a distant space with laughter, when he suddenly notices Shizuka and hides. He starts calling out to her out of nowhere, and Shizuka starts spinning around to find out who is screaming, and then notices that someone's hands have grabbed her heels, and Shizuka screams in embarrassment and runs away. Nobita closes the hatch to the distant space and decides to take a nap.

Meanwhile, at the Open Lot, Gian, Suneo and Shizuka discuss who could have done this to them. Doraemon shouts at them that this is all Nobita's doing. Realizing that it was Nobita, Gian, Suneo, Shizuka, and Doraemon begin to discuss how to teach Nobita a lesson for such behavior.

Nobita himself wakes up and sees that there is only a black background around him, which later changes to glare and flashes. He becomes scared and calls for help. In fact, all this turned out to be a dream when Nobita suddenly wakes up. He sighs with relief and decides to get out, but something is stopping him. He thinks that from this he can spend the rest of his life in a narrow remote space. It turns out that Doraemon, Gian, and Suneo sat down where Nobita made a hole into the remote space, so Nobita cannot get out of there and cries, begging his friends to let him go. Shizuka concludes that this will serve as a lesson for Nobita for the future.
