The show's title characters are a pair of alien brothers named Guapo and Fraz, both of whom work as couriers, who travel throughout their universe to deliver packages to a different planet in each episode of the series.

Sunbow Entertainment was an American animation studio and distributor, founded on June 23, 1980, and owned until May 4, 1998, by Griffin-Bacal Advertising in New York City and in the United States. Griffin-Bacal's first animations were animated commercials for Hasbro's G.I. Joe toy line. The success of the animated commercials led partners Tom Griffin and Joe Bacal to form the company. Due to their close working relationship with Hasbro, Sunbow came to be recognized as the toy giant's unofficial television arm.
