Muppet Mobile Lab, featuring Dr. Bunsen Honeydew and his assistant Beaker, has returned to Epcot this week! The Mobile Lab is a Walt Disney Imagineering Character creation that rides around Epcot interacting with guests. While the Muppet characters are riding around, they engage in a 6-8 minute comedy skit. Dr. Honeydew and Beaker first make their appearance in Epcot with the Muppet Mobile Lab several years ago during a limited time engagement. This week, it returned to Epcot, again, for a limited time. You can catch the Muppet Mobile Lab at various unannounced times throughout the day near the tip board behind Spaceship Earth.
