It starts off somewhat dark but the whole atmosphere is kind of relieved the way the characters Carl eats are depicted as unharmed inside him. I don't want to give away too much spoiler for those who perchance read the thread before watching the link.
This is superb! My gosh I love these Muppet people. It seems like every video is excellent in its own amazing way. Who would have ever thought at this time last year that we would see Big Mean Carl starring in his own YouTube video? Not me! Another home run for The Muppets Studio! Can't see what they have in store for us next!
