S1, E28: Chip and Dale are big fans of the police department. So they follow their friend, Plato, an English bulldog, and his master Detective Donald Drake in pursuit of Percy, a crook who had just stolen the Klutchcoin ruby. They retrieve the ruby, but Percy gets away. Back at police headquarters, Drake reveals that the robbery had all the earmarks of a Klordane job, buy supposedly Klordane drowned in the river a year ago. Meanwhile, Klordane (who's very much alive) sends his cat, Fat Cat, into the police station to steal back the ruby and plant evidence (gambling chits and an airline ticket) in Drake's overcoat. The police officers are shocked, so they lock up Drake and Plato.
