After their explosive escape at Graceland, twins Coke and Pepsi are ready to resume their trip across America--only now in a convertible instead of the RV. They travel through Arkansas and Oklahoma, visiting weird-but-true tourist stops along the way, and finally end up in Texas, home of the Weird Capital of the Country: Austin. The twins' many enemies--the bowler dudes, Mrs. Higgins, and Dr. Warsaw--all swear they're done chasing Coke and Pepsi for good. But when the twins start receiving more codes and ciphers from a mysterious robotic voice, they know someone's after them. They just have to figure out who before the mystery villain finds them first.
