The Electric Mayhem Bus debuted in The Muppet Movie and has become one of the most iconic Muppet vehicles. This psychedelic colored bus belongs to the Electric Mayhem, with the names of the individual band members adorning various sides of the bus, and is generally driven by Dr. Teeth. In The Muppet Movie, the bus allows for an intervention by the band, rescuing Kermit the Frog and friends from the desert, and carries the entire troupe to Hollywood. The bus resurfaced in the 1979 Macy's Thanksgiving Day Parade.
The bus features prominently in Muppets from Space, still boasting a 1970s paint job and interior decoration. The bus was also featured in Wendy's Kid's Meal promotions for the film.
Although visibly absent, it did merit a verbal tribute in The Muppets' Wizard of Oz, however. Commenting on the band's lateness, Floyd Pepper remarks, "We've been driving the same lousy bus since 1978."
