There may be 104 days of summer vacation, but Phineas and Ferb only have a week left to "do it all," so they decide to travel around the globe on a hunt for treasures to display in their backyard Museum of Cool in Quest for Cool Stuff. The innovative duo created the All-Terrain Transformatron (A.T.T.) in order to scale walls, drill through obstacles, and explore locations like an underwater cavern, a lost temple, and even the moon, all the while collecting silver sprockets to upgrade their A.T.T. with gear that will allow them to access new areas.<br><br>But just as in the cartoon series, a separate struggle is taking place unbeknownst to Phineas and Ferb, with their pet platypus Perry donning his signature fedora and foiling Dr. Heinz Doofenshmirtz's scheme to take over the tri-state area. Players control Agent P as he runs, jumps, clings to ledges, battles Norm Bots, and avoids the many booby traps in the Doctor's laboratory. As they play, gamers will also come across familiar characters like Candace, Isabella, Buford, and Baljeet, and players can also stop by the Museum of Cool at any time to take a look at all the cool stuff the boys have acquired.<br><br><! -- 3DS -- >
