Billy Bob, full name Billy Bob Brockali, was the mascot of ShowBiz Pizza Place, and one of two bears and two guitar players in The Rock-afire Explosion (the others being Beach Bear in both cases). With the exception of a period in the mid 1980s where ShowBiz Pizza Time produced its own Rock-afire showtapes, Billy Bob has been voiced by Aaron Fechter.
Billy Bob was derived from Billy Wilbur, a character in The Hard Luck Bears animatronic show. Billy Bob's first appearance at ShowBiz Pizza Place was as a walk-around character at the first ShowBiz location at Antioch Shopping Center in Kansas City, Missouri. The character was named after two people: ShowBiz Pizza founder Bob Brock, and Creative Engineering artist David "Billy Bob" Irvin. At the request of Stan Emerson, who worked for the advertising agency hired by ShowBiz, Billy Bob was given red and yellow overalls, the colors of ShowBiz Pizza.
Billy Bob's first appearance as an animatronic character was with the launch of The Rock-afire Explosion. Billy Bob originally spoke with a heavy country accent, but this was later softened.
Billy Bob's stage, shared with Looney Bird, as originally designed, was designed to resemble a gas station, with the "Smitty's Super Service Station" backdrop, a gas pump, and an oil barrel. Some skits were written around the Smitty's theme, discussing Billy Bob's invention of gasohol (also called "Goofy Gas"), an alternative for gasoline that was also drinkable.
In the later years of ShowBiz Pizza Place, Billy Bob's stage was redesigned as "ShowBiz Pizza Campground". In this new stage design, the Smitty's backdrop was removed, Looney Bird's oil barrel was painted green, the trees from center stage were relocated to stage left behind Billy Bob, and a new lamppost with a sign reading "ShowBiz Pizza Campground", in the style of the later logo, was installed. This stage was exclusive to ShowBiz; Rock-afire installations at other restaurants retained the Smitty's backdrop.
During Concept Unification, which occurred at most of the ShowBiz Pizza locations between 1990 and 1992, Billy Bob's animitronic was completely removed from the stage.
It should be noted that, Pasqually and his drum set were moved to Billy Bob's former position on the stage.
