The Concept Unification Prototype stage is a stage format that was tested as a method of replacing The Rock-afire Explosion at 3-Stage locations with the Pizza Time Players, using a house theme for the stages. This stage was never installed in a ShowBiz Pizza Place restaurant.
Rock-afire shows would ultimately be replaced, via Concept Unification, with Munch's Make Believe Band, which retained certain elements from The Rock-afire Explosion that the company considered desirable. These elements included Mitzi Mozzarella's appeal to young girls, Fatz Geronimo's strong center stage presence, and the "band" format.
Designed by Jul Kamen, the Concept Unification Prototype stage consolidated the three stages of The Rock-afire Explosion into two stages, consolidating center stage and stage left into a single stage. The stage was designed to appear like the interior of a house, which was similar to the "house" theme at existing Chuck E. Cheese stages such as the Rocker Stage and the C-Stage. Pasqually was on Stage Right, while Helen Henny, Chuck E. Cheese, and Jasper were on Stage Left. Mr. Munch was inside a red barrel next to Pasqually. Also, his position in the show was one of the most unique, in that five animatronics would allow him to travel around the two stages.  Stage Left also had a vase with the Singing Flowers in it.
In this stage design, most of the characters were placed on different animatronics than would later be done for Munch's Make Believe Band.
