After all the good I've talked about The Powerpuff Girls, it's time to talk about a moment where they gave into pressure and said No Girls Allowed!
One of the most notable moments of nudity-related humor came all the way in the first season, with the episode "The Bare Facts." In that one, Mojo had attempted to become Mayor, so he had to strip the existing Mayor of... something, something which led the Girls to laugh and laugh. We got our answer at the end, where the Mayor had been shown to be stripped of more than his powers... in a very personal way.
Three seasons later, in the episode, "Nano of the North", nanobots invaded Townsville via raindrops to destroy everything made of carbon (except evidently people for some reason), including buildings, cars and clothing. So when the Girls tried to fight them at full size, they failed, and they had to return home naked. Unfortunately, a series which used to do episodes like "Down N' Dirty" unashamed now embraced cowardice and comparatively censored the Girls, with them covering their butts and their fronts hidden by the Professor's arm.
It's a little weird why they'd chose to do that, given Craig is an unconventional person who does weird things in his cartoons. I have a hunch, though, that it was because at the time, the series was also airing on Kids WB, which was broadcast television on Saturday Mornings. That kinda thing is comparatively censored, and, in fact, this episode debuted on Kids WB, hence the probable need for censorship.
Nonetheless, it is an error, and it needs correcting, so I put Krizeii to task on creating a new version of the scene with less censorship. Considering later on one of the Rowdyruff Boys shows their butt, I don't think kids would mind. They'd more than likely see it as funny, since they laughed so much at the Mayor all those years earlier.
How sad that after years of bravery, they so suddenly embrace cowardice. What a waste.
