Wow, I love how they really pulled this off. It looks seamless on certain parts. I see this further in the future. The first clip is the movie and the behind the scenes. The instant gratification of animated movement and character life is really fun in puppetry. The best is doing karaoke to your favorite songs too.
For a bonus a clip of the Henson muppeteers in action. When workin' on their own projects, surprisingly for the older crowd. Wanting to dabble with this in the future no doubt. Stay Tuned..
