Top Secret Spy Strategy / Hello, Alien

Top Secret Spy Strategy

When Nobita breaks a vase belonging to his teacher at school, Suneo uses this to blackmail him into doing work for him and becoming his slave. He tells everyone that Nobita will listen to whatever they ask when they say "vase". However, Nobita had enough of the vase incident and runs away fearing that he will be asked to do more work for them. Doraemon gets very angry when he hears, and together with Nobita decides to get Suneo back by spying on him to discover his weakness.

At school, they restore the vase back to its original state. Back home, Doraemon takes out the Spy Set (consisting of a camera and a microphone dressed as spies) to track Suneo's whereabouts. After watching Suneo's activities during the afternoon, they finally find Suneo's weakness - wetting his shorts while sleeping - and decide to use this incident to blackmail Suneo back.

Suneo angrily calls Nobita, who claims he had forgot about the "vase". He returns to school to find the broken vase restored. Frightened, he breaks it. He finds himself in Nobita's shoes when Nobita blackmails him back, and when Nobita is told to use his hands to balance himself while barking half-naked, it is Suneo who does so instead when he hears the word "vase".
