Geo and Dr. Brain were literally up the creek without a paddle when they ran out of power in Phi Phi"s digestive system, and things only got worse when, right when they thought they"d be home free, they were taken into the circulatory system! The situation has got Geo"s friend (and Dr. Brain"s assistant) Kay frantic, and Phi Phi thinking Kay cryptic. When she decides to go to a traditional game festival, it"s time for everyone else to get serious, because SURVIVAL IN THE HUMAN BODY is anything but a game!
