I've been itching for a Pigs in Space movie, too. I like your idea. I wish Diz would steal ideas from the fans, though! HA HA! Just, in payment, give us a free DVD, soundtrack, and one of each of the merchandise items made from the film. I think that'd be fair.
Especially with the latest $160 Millenium Falcon playset that was recently released. Can you imagine a full size action figure playset with Muppets to go in it of the Swinetrek? COOL!
I always saw it as Link, Piggy and Strangepork are showing the Swinetrek to the other Muppets when Link accidentally sets off into space via hyperspace and end up in a new galaxy where some evil warlord thinks they're there to attack his planet.
With the whole Gonzo thing: I'm okay with the alien thing, especially since they didn't give them a species name and therefore he is still labeled a Whatever. I suppose, then, knowing his history, that Frackles must be Muppets that came from space?
