Spy War About Top Secret - S1.E9

The episode starts with Nobita breaking his teacher's vase while he was cleaning the classroom with Suneo. Suneo agreed to help Nobita cover up his crime, on the condition that he must do whatever Suneo wants. Fearing his teacher, Nobita reluctantly agreed. Along the way, Suneo and his friends taunt Nobita about the vase. Doraemon furiously takes out a tool that spies on Suneo's house, and Nobita found out that Suneo had a habit of bedwetting. Suneo's plan backfired when Nobita taunted him with his secret bedwetting habit. In the end, Suneo's friends wanted to taunt Nobita by making him do a headstand and bark like a dog, but Suneo, fearing that Nobita may uncover his secret, did the headstand.
