This was the first Walt Disney film released to theaters that was animated, not by the Disney "Feature Animation" division, but by the "Television Animation" division. This explains the notable difference in quality between this film and other Disney animated releases around the same time (for example, The Little Mermaid (1989), The Rescuers Down Under (1990), and Beauty and the Beast (1991)). The Television Animation division has since produced several other theatrical releases, such as A Goofy Movie (1995) and Peter Pan 2: Return to Never Land (2002) (with striking improvements in animation quality), as well as numerous direct-to-video sequels for Disney features.
There were originally plans to have a Chip 'n' Dale Rescue Rangers (1988) movie released the summer following this movie's release, along with a Goof Troop (1992) movie. However, Disney decided to pull the plug on that project, and retool the Goof Troop movie into A Goofy Movie (1995), since this movie underperformed at the box-office.
Side characters from DuckTales (1987), like Gyro, Doofus, Bubba the Cave Duck, and Gismoduck are absent, as the filmmakers didn't want to confuse newcomers who have not seen the Disney Afternoon cartoon. This is also why none of any of the show's villains, like the Beagle Boys, Magica DaSpell, and Flintheart Glomgold are present.
Chuck McCann's only Theatrically Released Animated Film. The only other animated film he appeared in was Mickey's Twice Upon a Christmas (2004), which was also from DisneyToon Studios, but was instead released straight-to-Video/DVD.
