S4E16 A Prize in Every Package

In Chicago, a group of thieves breaks into a jewelry store and hides their stolen treasures in a grain bin. The valuable jewels are later packed into Crickly Wickly cereal boxes and sent to Hooterville. While Lisa recognizes the gems as the real deal, Oliver believes they are merely costume jewelry. After having them appraised, Oliver finds himself in hot water when the sheriff apprehends him, suspecting him to be involved in the jewelry store robbery.
