After teasing fans with several parody trailers, the folks behind 'The Muppets' have finally released a full-length trailer for their upcoming return to the big screen.

As the trailer reveals, 'The Muppets' revolves around the beloved gang getting back together again after splitting up years ago. Not only do we get the usual Muppet suspects -- Kermit, Miss Piggy, Gonzo, Fozzie, and many others -- but a new Muppet named Walter. And if all that wasn't enough there is a rival band of tough puppets who arrive to challenge the Muppets...the Moopets!

Since they have to update things a bit there are some unfortunate bodily function jokes and a scene where the Muppets sing Cee-Lo Green's "Forget You." (What is this, a 'Shrek' movie?) Of course, it's still the Muppets so they can't really sing the original lyrics of that song.

Look for cameos from an array of stars, including Jack Black, Neil Patrick Harris, and Sarah Silverman when 'The Muppets' opens on November 23.
