Imagine if The Muppets lab with Bunsen and Beaker relocated their lab to the Imagination pavilion, to do experiments specifically on Imagination. They create a machine (going back to the despicable me ride system idea) that can travel inside the minds of tourists... Could be very humorous, and interactive with the audience. Cameras set up similarly to Laugh Floor Comedy Club. "This is our next victim" the simulations go inside his brain and theres just a bunch of paperwork and responsibilities... So Beaker uses different tools to get his fun imagination side going...
Stuff like that. I feel like a Muppets lab would be a perfect fit for Epcot. Could even have an interactive muppets lab area.. As well as the Muppets Mobile Lab relocating to outside the theatre entrance.
