Mandarin Island

Butch and Cassidy attached Drowzee to a device that would amplify Drowzee's hypnotic waves and broadcasts it through a parabolic antenna on the roof of their base. Officer Jenny and James found their base after Meowth was controlled by the effects of their device. James famously got Butch's name wrong once again and called him "Botch". Butch revealed that Giovanni himself came down to the police station and bailed Butch and Cassidy out of jail but he and Cassidy end up arrested by Officer Jenny once again after their Mandarin Island base was destroyed.
