Das Coffeehaus, a brand new, chic coffeehouse chain, opens its doors and becomes incredibly popular... literally overnight. The chain's signature treat is a dip in the ""Perkolator 9000,"" a crazy machine that submerges patrons in a full-bodied coffee bath. When perky patrons are suddenly reported missing, Jerry sends the girls in to investigate. What they discover is an evil Barista brewing up a mighty revenge from his underground beanery/lair. In a b-story, Mandy discovers the spies' secret… and, impressed by her tenacity, Jerry decides to make her a spy!
