Goelz obliged with an overemphatic "NO!" This earned his first laugh from the crewmembers. As Goelz increased in confidence, and Gonzo transitioned from a nervous depressed failure to a manic, confident stuntman, other facets of the character fell into place. The second season introduces his romantic fascination with poultry. As the performer reminisced in Of Muppets and Men: Other Muppets In addition to the starring role of Gonzo, during the first season of The Muppet Show, Goelz also had the slightly less challenging but still time-consuming supporting roles of Zoot and another new creation, scientist Dr. Bunsen Honeydew. In later seasons, a new Goelz character was added, the well-meaning but slow-witted janitor, Beauregard: Fraggle Rock With the debut of Fraggle Rock, Goelz was cast as one of the five leads, the depressed, pessimistic Boober Fraggle. Boober stemmed from something Goelz had said while working on the first season of The Muppet Show, that he was so busy on the show that the only things he had time to worry about were death and laundry. At Muppetfest, Goelz related the process of character creation for the show: "They looked at the performers, and picked out our flaws, and made characters out of them. They denied it... So that's how I ended up with Boober, the superstitious, paranoid character." In the Fraggle Rock: Complete First Season interviews, Goelz also mentioned that "I was cast with Boober, who was sort of grumpy and inflexible, just like I could be a lot of the time." Demonstrating his versatility, he also played the pompous Uncle Traveling Matt, the rat-like Philo, and the cantankerous World's Oldest Fraggle, as well as a variety of guest characters and memorable incidentals, such as Wrench, Cotterpin Doozer's best friend, the obese Large Marvin and Sidebottom, Boober's more jovial alter-ego from his dreams. In the Fraggle Rock: Complete Second Season interviews, Goelz talked about how he developed Traveling Matt's character, from the starting point as Matt being simply a misinterpreting chronicler of human life, to determining that Matt was also inherently clumsy and inept, which led to Matt covering up his blunders in his postcards and developing a comedic air of ostentation. Goelz reprised his roles as the voices of Boober and Travelling Matt in the 2020 Apple TV+ spin-off series Fraggle Rock: Rock On!; the two characters were puppeteered by John Tartaglia, who also puppeteered Wembley (to Frankie Cordero's vocals)
