It's not linked from muppets.com, though it should have been. It's called disney motion, I'm not sure of the url, but if you do a search for "disney motion" you should come up with it. You have to download the soft ware, you need internet explorer, you need to downlod all the videos as well. The Muppet one was deleted becase they only play like 4 at a time and if you miss it after a certian amount of time they delete it. Perhaps someone saved it.
BTW, I asked for a definition of all things moral, not examples of what you find immoral in the movie. My point being that morality has not set definition, unless you take it from the Bible and since the Mupets are not a church morality is subjective. Perhaps you found things objectional, but I did not. It's all subjective because there is no definition of decencey or morality. You can define all things that are rocks, or all things that are plastic, but not all things that are moral. And you could tape the special, watch it, and then let you kids watch it. It's what I would have done.
