The Big Cartoon Database has the official synopsis for Mickey’s Three Musketeers: “While pushing a broom in Musketeer Headquarters, Mickey dreams of the ultimate promotion to Musketeer-hood. But he knows that he and his coworkers, Donald and Goofy, have a long way to go. That is until Peg-leg Pete, captain of the Musketeers, and his sinister lieutenant, Clarabelle decide to use them in a dastardly plot to rid the kingdom of Princess Minnie – the only mouse standing between Pete and the throne! Pete makes the trio official Musketeers and assigns them to ‘protect’ Princess Minnie, assuming they’ll fail to get the job done. But what Pete hasn’t pegged on is the fact that Mickey, Donald and Goofy are about to learn an invaluable lesson about friendship, teamwork and the true meaning of ‘All for one and one for all!'” Mickey’s Three Musketeers directed by Donovan Cook and with original music by Bruce Broughton (who also worked with Mickey on the 1990 Prince And The Pauper featurette), is set to hit DVD and arrive in stores on August 3.
