"When Buford challenges Ferb to a good old-fashioned yo-yo showdown, the competition is on! Phineas and his friends build a western town and host the draw of the century. At the same, the evil Dr. Doofenshmirtz has built a life-size pogo stick, which he hopes will finally destroy the Tri-State Area! Will Agent P stop him in time? Or will Danville be smashed to pieces?"--Publisher.
