Kenichi, who is easily deceived by Kemumaki, is in a bad mood, but due to a misunderstanding by a police officer, he is ordered to pick up empty cans on the side of the road.

今日はエイプリルフール。ケムマキに易々とだまされて不機嫌なケン一は、お巡りさんの勘違いで道端に落ちている空き缶を拾い集めるよう言いつけられてしまう。そこでケン一は、「空き缶を集めて公園に持っていくとお菓子がもらえる」という嘘を思いつくのだが、その噂は瞬く間に町中に広がっていって…。
