Just a bit of armchair imagineering here - for a while now, I've had this idea for a Muppets dark ride. It's sort of a cross between Peter Pan's Flight and Mr. Toad's Wild Ride, the plot being that you're part of a "Daredevil Academy" that Gonzo set up (behind Kermit's back, of course). In the queue, there's an animatronic Gonzo telling us that today, you'll be learning how to, I don't know, do a stunt involving a rocket or a jet pack or something that flies. You get in the ride vehicle and (of course) the stunt goes wrong and you're sent flying all over the Muppets Studio, with scenes like the Swedish Chef's kitchen, Muppet Labs, and maybe the ride could take you out of the studio and into other locations like a jungle (featuring different Muppet animals a la the Jungle Cruise) or outer space (specifically, the planet Koozbane). Eventually your vehicle finally slows down and as you head to the unload area you go by Kermit screaming at Gonzo for doing something so incredibly irresponsible and dangerous while Gonzo reassures Kermit that the NEXT class will go much better.
The whole thing would be jam-packed with references to Muppet productions, cameos, and gags. One gag I thought of, for example, is that at one point during the ride Rizzo appears with a camera and takes your picture. And then, after you unload, you go by Rizzo again, who offers to sell you the photo for a large price.
I'm still ironing out all the details, but what do you all think?
