Gollywood stars Brittany and Mary Pat, also known as The Wholesome Twins, are arguing over the size of their squares etched in the floor. Mary Pat accuses Brittany of making her square bigger, and the CyberSquad steps in to check if her claim is true. Brittany shows the squad how she measured the size of the square, and she started at the 1 inch mark instead of the 0 inch mark. After Matt, Inez, and Jackie explain that she needs to start any measurement at the 0 inch mark, they measure both squares again and find them to be the same size.
