The original working title of Craig McCracken’s student film that developed into The Powerpuff Girls was Whoopass Stew!
McCracken created the early short while he was studying at the California Institute of the Arts. The concept featured three superpowered girls and the basic visual idea that later became the television series.
The title was changed before the project reached Cartoon Network because the original wording was considered unsuitable for the intended children’s audience. The revised project eventually became The Powerpuff Girls, with changes to names, presentation, and story details.
The student film is important because it shows the series’ origin before the familiar television branding existed. It is not the title of the 2002 theatrical movie or of an episode from the finished series.
