Miles and Niles find themselves marooned for the summer at Camp Good Times, which is all about peace and good vibes. (Can you say BOR-ING?) With no clear prank-ortunities, the Terrible Two fail to see what about all of this is so good. But when kids from the nearby Yawnee Valley Yelling and Push-Ups Camp raid Good Times' super-secret candy stash, the campers look to Miles and Niles for help. Will our heroes break free from the feckless feel-goodery of Camp Good Times? Are their sharp minds and close friendship a match for the fists of the rival campers? And why has Stuart changed his name to Tree?
