There are a few Pokemon episodes that haven't made it to American shores for various reasons, either because they're a little too seizure-inducing, a little too violent or just racist enough.
The show's kind of fucked up.
In Beauty and the Beach, Team Rocket enters a "Beach Beauty and Pokemon Costume Contest" as part of their ill-defined nefarious scheme to kidnap Ash's Pikachu so it can power a doomsday device. And because it makes more sense than anything else in the history of the show, this means the male character James has to throw on a pair of giant breasts for the swimsuit portion.
What kind of swimsuit competition allows two people who are clearly adults to compete against children is unfortunately never explained. Scenes from the uncut Japanese episode have found their way to YouTube but are unfortunately in Japanese with no subtitles.
