How Do Muppets Go Outside?

We are used to seeing the Muppets on a studio set, where the puppeteers are beneath the floor- although we habitually suspend our disbelief and don't think about them. So who's controlling the Muppets when they go outside and show their entire bodies? Today, they might use GCI, but that wasn't really a thing when Emmet Otter's Jug-Band Christmas aired in 1977 or when The Muppet Movie came out in 1979. Jim Henson and his crew had to think outside the box, literally, to put the Muppets in the real world. How did they do it? In many different ways, depending on the scene. They might come up with a brand new elaborate method just for a few seconds of film, but it was worth it in the end. Alex Boucher shows us how Kermit sang in a swamp, how Fozzie Bear drove a car, and how a group of Muppets rode bicycles. The real wonder is that even when we know how it's done, even when we can see the puppeteers at work, we still consider the Muppets as distinct characters with their own personalities.
