I actually don't mind the suggestive stuff. It's not like kids will understand it anyway. I don't see why people get worked up about trivial things that are supposedly suggestive. Actually Spongebob was always a dirty cartoon. His show sort of falls a tiny bit into the 'gross out humour' genre. If you see the earlier episodes, it's style is very gross out humour. Other cartoons that do fall into that category would be Ren and Stimpy and Ah! Real Monsters. Nickelodeon actually screens an enormous amount of gross out humour series. I'd say Brandy and Mr. Whiskers would also be a gross out cartoon. I didn't really like them, I also don't think the show's very well thought out (sorry! D8).
The reason why they have the Girl in Winnie the Pooh was that Pooh was based off a book; and Christiphor Robin was based off the author's son. The real Christopher Robin died so Disney don't have the right to use him anymore. So yup, the weird girl is in.
They don't show any of the new seasons of cartoons here actually. They still replay the old episodes over and over again. It's one of the reasons why I don't watch Disney anymore. xD
