The Hacker challenges Jackie, Matt and Inez to a contest on cyber-wide television! In order to prove to all of Cyberspace that Hacker is not as powerful or smart as he seems, the kids return to Topsy-Turvy Island on the Northern Frontier for the contest. Their mission is to power up a Mini-Wreaker using cyber-fireflies of varying power before the island turns inside out at sunset. The kids must use algebraic equations to determine how many Gleamers and how much power they’ll need.
This is the first time where Matt calls Inez "Nezzie".
- Math topic: "Find Those Gleamers!" focuses on basic algebra, such as simplifying equations by using letters.
- For Real Segment: "That Suits Me Fine": Harry is shopping for a "new look" that he's saved $100 for, and he wants to find something that costs the most his money will buy.
