The game is based on the Warner Bros. series of Looney Tunes cartoons featuring Ralph Wolf and Sam Sheepdog.

After another failed attempt at stealing a sheep from Sam Sheepdog, Ralph Wolf returns home after his shift to relax and enjoy some television in his chair.

Despite many obstacles and encounters with various characters such as Porky Pig, Elmer Fudd, Yosemite Sam, Gossamer, Toro, and Road Runner, Ralph is finally able to steal Sam's entire flock, but as he is declared the winner, Marvin the Martian gatecrashes the show, angry at Ralph and Daffy because a specific sheep that Ralph was forced to fire into the sky using Yosemite Sam's cannon in order to win actually landed on Planet X while Marvin was experimenting with his instant Martians, causing a serious accident which led to the Martians scattering across the planet.

The goal of each level is to steal one of the sheep from Sam Sheepdog's flock without him noticing and escort it to a marked area.

Ralph is able to jump, tiptoe as to not make noise, and dash in case he needs to escape from danger.
