Here's my tribute to Pigs in Space and the various aliens that the Muppets encountered during the course of The Muppet Show.     I had originally intended this to be a concept for the welovefine.com  Muppets T-shirt contest. The idea was that nothing would be more  adventurous - or dangerous - than being a "red shirt" on the Swine Trek.  But since the contest was only open to residents of the US, that plan  was, well, shot into space.
