No one knows how to cure the summertime blues better than Phineas and Ferb. The stepbrothers - and stars of the hit Disney Channel series - are out to fill their summer vacation with the most outrageous things they can think up! Play as Phineas, Ferb, and Agent P as you dream up amazing inventions, hurtle through insane race courses, and more. Find gadgets and parts for your inventions in locations from the show. If that wasn't enough to keep you busy, there are mini-games to play, a big sister (Candace, ugh!) to avoid, and a world to save as Secret Agent P squares off with the evil Dr. Doofenshmirtz.
