Really good movie...shame about the swearing!

This is one of the all time greats for cartoons, with lots and lots to keep mum and dad very entertained, the little ones wont understand the meaning behind the well thought out plot, but still enjoy it all the same, however very shocked to find swearing it! I would write down what was in it but fear being banned? Totally unsuitable for my six year olds ears luckly she didnt seem to pick up on it. It should in my eyes have been rated a PG13 or just take them out as they dont add anything to the movie.
