The CyberSquad needs to pay the toll to make it across the bridge. Instead of money, the trolls want the same number of scones as the number of warts on a troll's face. The CyberSquad members count the number of warts on each troll's face, and after Jackie stacks the counts, they find that an equal number of trolls have 4, 5, and 6 warts. They look for the middle number that splits the group evenly and decide to pay a toll of 5 scones.

In order to make progress toward finding Hacker's time machine, Matt, Inez, and Jackie must help a gnome determine how many rocks were used to create a stone heart. The hearts were broken down into five piles of rocks. They count the number of rocks in each pile and choose the number that occurs most frequently as the answer.

The numbers sing about hiding behind each others because they are smaller.

Explains stratified random and sampling and clusters.

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.
