Scrapyard Dog, originally released for the Atari 7800, starts with Louie's dog Scraps being kidnapped by Mr. Big, who has driven off with Scraps and unleashed (get it?) a band of thugs to stop Louie. Louie must dodge the thugs' attacks while avoiding other enemies, hopping over obstacles, darting under bird droppings, and collecting cans and money.

With only shrinking pills as weapons, Louie will run from junkyard to city to forest to mountain to desert to snowfield to the final castle in his journey to save Scraps.

In this run, Noxxa makes his way through many strange places in order to save his beloved dog.
