Peeking-a-boo Hat

Suneo knows the owner of the comic book store, so he buys the latest comic in advance. He shows it off to everyone at school. Everyone wants to borrow it, but he refuses. Then Gian comes and borrows it by force. Gian is in math lesson, and the teacher is writing on the blackboard. When he hears Gian's laughter, he immediately calls Gian. Gian stands up and immediately finds the comic in his hand to read. As a result, the comic is discovered and confiscated by the teacher. Suneo is very angry and asks Gian to find a solution, otherwise he will give the zero-mark test paper that Gian leaves with him to Gian's mother. Gian is very anxious and asks Nobita to find Doraemon to find a solution, otherwise Gian will make Nobita unable to leave the house. Doraemon then takes out the "Peeking-a-boo Hat" of the tumbler, and Nobita wants to sneak into the staff room to get the comic back, but when he is outside the window, the teacher sees Nobita and hurriedly runs away. At this time, Shizuka happens to chase the fleeing Pee-chan, and Nobita lends his hat and "Take-copter" to Shizuka, and soon catches Pee-chan. Nobita sees Shizuka using it smoothly and gains confidence, so he follows behind the teacher and prepares to take action, but a bee happens to come, which scares Nobita and makes him move his body and is discovered by the teacher. At this time, the teacher meets Gian and says that the comic can be returned to him, but he has to go to Gian's house to talk to his mother. Gian is scared and hurriedly says that the comic belongs to Suneo. As a result, the teacher changes to Suneo's house. Nobita sees it and goes to inform Suneo. Suneo is very angry and borrows gadget from Nobita to take revenge on Gian. He secretly replaces the comic with a comic with Gian's name on it, and also puts Gian's zero-mark test paper in it. So when the teacher goes to Suneo's house to talk to Suneo's mother, she finds that the things belongs to Gian, and finally decides to let Gian's mother teach Gian a lesson.
