episode description
When Janay challenges Andre and Aubrey to a bubble blowing battle, they think outside of the box for a way to blow away the judges, including 11-year-old Kid Investigator Kaedence. They decide the best way to upstage Janay is with a bubble in the shape of a cube. When things don’t go according to plan, Janay wins fair and…circle? Will they be able to square why bubbles are always round?
