You were a new mechanic at Circus Babys Pizza World when you got assigned to the day shift, whatever. You walked in when you saw that the place was closed down for a "Mandatory Cleaning Day" You unlocked the doors and walked inside when you were suddenly spraying with something. You started to shrink down from an shrinkage liquid that was meant to shrink down crumbs, lost pizza and stains into nothing. But that would include whatever unfortunate souls that was sprayed with it. You shrunk down more and more, with the filth as the animatronics all turned on, turning into cleaner drones, including Circus Baby, Ballora, The Minireenas, Funtime Freddy, Bon Bon and Funtime Foxy, meant to clean up whatever shrunken filth... Including you!
