Phineas and Ferb want to get the most out of their summer vacation, and that means they're gonna have to put some work into their plans. No beaches or campouts for these best buds-we're talking a time machine, a backyard roller coaster, and maybe even the world's largest drop of water. It looks like this summer just can't be boring! Unless of course big sister Candace manages to bust them-or worse, if the evil Professor Doofenshmirtz somehow manages to take over the Tri-State Area. And if that wasn't enough, their pet platypus Perry is. hey, where is Perry, anyway? Hang out with Phineas and Ferb on the coolest summer break ever in part three of this colossal comic collection!
