Summer vacation means unlimited possibilities for Phineas Flynn and his stepbrother Ferb! Every day, the inventive duo cook up wild new projects that stretch the limits of imagination--much to the frustration of their sister Candace, who never stops trying to expose them. No matter how close she gets, their antics always slip past unnoticed. Meanwhile, the family pet Perry the Platypus has his own mission: keeping the bumbling but persistent Dr. Doofenshmirtz from conquering the Tri-State Area. As Agent P, he's always one step ahead, ready to foil another outrageous "inator" scheme. Phineas and Ferb: Classic Comics Collection, Volume 6 gathers more of their laugh-out-loud comic escapades in their original release order--many appearing in paperback for the very first time!
