Bill Prady is a writer who wrote or co-wrote many Muppet productions and appearances. Early in his Henson career, Prady served as editorial assistant on the documentary Down at Fraggle Rock. He subsequently wrote for the animated version of Fraggle Rock and penned stories for the Muppet Babies Comics (including the Star Trek parody "Out of this World," "Upside Down Land," and several others), as well as comic stories for Muppet Magazine (including "A Doozer Dilemma" from the Fall 1988 issue).
Subsequent projects, with the foam Muppets themselves, included Muppet Meeting Films, The Jim Henson Hour, Miss Piggy's Hollywood, The Muppets Celebrate Jim Henson, Muppet*Vision 3D, and Muppet Classic Theater, as well as Muppet appearances on The Cosby Show and Disneyland's 35th Anniversary Celebration.
In 2006, Prady wrote and produced a short presentation pilot featuring the Muppet characters. The pilot for a possible series was shot in "mock documentary" style and focused on the Muppets' efforts to launch a network television series. The presentation pilot was directed by Bill Barretta and featured puppetry by Barretta, Dave Goelz, Steve Whitmire and Eric Jacobson.
