Well... I never got around of watching older seasons because of school and other things, I'm sorry If that come out as something wrong though.That's really ridiculous. They've already featured Lopunny multiple times in the anime with no problem. It was featured in the episode where Dawn and Buneary were taking part in a fashion show and was used in the Sinnoh Grand Festival. I think that you're taking the whole Playboy Bunny inspiration too seriously when it's never been shown as sexual in the anime. It's just a tall brown bunny. There's nothing inherently sexual about its design and unless you look up its trivia on sites like Bulbapedia, I don't think most people would assume what it's based on. There wouldn't be anything to censor or anything that warrants removing the episode. As far as I can tell, none of Lopunny's appearances in the anime or Adventures manga have been edited or banned in different countries, so I don't understand why you'd think it would be such a huge problem.
