A smart kid who lives with his big brother, Marvin, above the family store, Sneaky Pete is collecting equipment for a Big Adventure he's planning, and loves to visit Patrick's Pawn Shop and Military Supply. One evening at the pawn shop, while sifting through the discount section, he overhears Patrick talking in the office. Pete hears Patrick say Marvin's name and something about a valuable gold coin-and then he talks about his plan to steal it! Could a Big Adventure be brewing? Join Sneaky Pete in a fun tale that includes a creepy mansion, robot guard dogs, paragliding robot cats, a dark sewer system called the Sewie Hole (home to a talking rat and his friend Jim), a talking alligator, missing parents, a spy and his twin brothers, gyrocopters, a couple of rich girl twins, Jack the Hawk, and of course Marvin.
