The Mini-Stage is a stage format designed for smaller ShowBiz Pizza restaurants operating in smaller towns and cities to present The Rock-afire Explosion during the early 1980s. The stage used a modified version of the show, displaying only four characters. Due to this only lasting for a few years, the Mini-Stage saw very limited usage.
Although only five Showbiz Pizza restaurants used the Mini-Stage, a few are known to still exist.
In 2002, a Mini Stage was purchased by Hillwood Strike and Spare in Nashville, Tennessee and was restored, but later put on static display in a state of disrepair. In 2015, the Funtown Mountain amusement park in Kentucky bought it and was likely going to be restored to operating condition along with the Wolf Pack 5, if not for the bowling alley's closure the previous year.
Another surviving Mini-Stage is Billy Bob's Bear-a-dise Tropical Jamboree, which is a traveling show that preformed at the Kentucky State Fair in 2012, 2014, 2015, and 2016, the St. Joseph County Fair in South Bend, Indiana in 2013, and at the Big E Fair in Springfield, Massachusetts in 2015 and 2016. However, this show is in very poor condition. As of November 2016 Aaron Fechter is repairing it.
