Phineas and Ferb: Sipping with the Enemy/Tri-State Treasure: Boot of Secrets

When the boys ask Candace to decide what they should do for the day, she slyly asks them to invent a device to attract their Mom so that she can finally bust her brothers. Meanwhile, Dr. Doofenshmirtz has invented a "Baby-Cry-Inator" designed to tarnish his goodie-two-shoes brother's image with the electorate./ When Baljeet becomes concerned that he is losing his mental edge, the boys invent a cerebral stimulatory hat, or "Brain booster," to help him. But when the hat exceeds expectations and makes Baljeet exponentially smarter, he suddenly views everyone else as beneath him and becomes a threat to civilization. Meanwhile, Dr. Doofenshmirtz plans to use his "Key-Find-Inator" to collect all the keys in Danville in hopes that it will lead to the Key to the City.
