Episode 978: The Case On the Opposite Shore
Scenario: Conan and Detective Boys who came to the park for bird watching start observing humans on the other side of the river with binoculars to "improve reasoning power". While playing with a profession, He finds Detective Takagi in disguise staking out. Apparently, cash is being handed over in the kidnapping case. He tries to go to the other side, but it takes time to move, so he keeps watching. After that, the criminal appears in the handing over the cash and is secured, but Conan gets caught. The criminal was not a kidnapping case, but a victim of a special scam. The Detective Boys begin observing the person who seems to be the criminal.
Conan, Haibara, and the Detective Boys are watching birds, but Conan proposes another game to them called "human watching". While teaching the Detective Boys how the game works, trying to determine people's jobs and occupations by watching them, they stumble upon detectives Takagi and Chiba apparently on a stakeout.
