Fortunately for him, the little windy town of Bottowa has a powerful energy source that'll put new pep in his step. Unfortunately for the Bottowans, this power source is what raises the big ball at the stroke of midnight on Reboot Eve (like dropping the big ball in Times Square, but in reverse), and their celebration is being broadcast live across Cyberspace! When Hacker steals the energy source, Delete is so upset that he decides to stay behind and join forces with the CyberSquad, who have come to help the poor little town from Virtual World-wide humiliation. To do this, they'll try to harness the natural power of the wind and build a giant windmill. But will they be able to finish it all by the stroke of midnight? And will Delete decide to stay in Bottawa forever?

(topic: Codes) - In the watery depths of cybersite Aquari-yum, the kids and Hacker go in search of a giant cyber-slug, who feeds on pure energy. The kids and Digit travel underwater in two separate vessels, but Hacker has a listening device that taps into their communications system, allowing him to overhear their plans - and track every move they make. The kids outsmart Hacker by devising a series of codes so they can send messages back and forth in secret - even though Hacker can hear what they're saying. But unless the kids can reach the slug first, Hacker will use the slug to attack Motherboard's circuitry and disable her once and for all! The Big Idea: You can use a code (a communication system that substitutes one thing for another) to send top-secret messages as long as your code has an adjustable rule that can be reversed to read the message.

The Leaders of Cyberspace have gathered to discuss Hacker's increasing influence, when they are suddenly interrupted by Hacker. Buzz and Delete, Hacker's henchmen, hide the leaders including Dr. Marbles, in the building and its' up to the kids to rescue them. Before long, the kids discover that they can only move between the building's levels by scaling its outside walls! So the kids turn the building into a giant ruler in order to keep track of the floors. And when they discover that there are levels beneath what they thought was "zero," the kids must tap into the power of negative numbers. The Big Idea: Numbers don't have to stop at zero! Negative numbers -- numbers that are less than zero -- can extend the range of what you can measure on a scale and give you the ability to compare numbers using direction as well as amount. Math Topic: Negative Numbers NCTM Links: Number & Operations.

Can they also help save its future?

Hacker decides that he can force cybersites to surrender by annoying them big time. He broadcasts his loud and obnoxious voice across the vastness of cyberspace from a massive statue shaped like the arrogant Hacker himself. The kids and Digit are sent by Motherboard to the Northern Frontier, where they carry out a Mission Impossible style scheme to silence the statue and disable Hacker's intimidation. Using their skills at measuring length, the kids make their way up through the inside of the booby-trapped statue to Hacker's pointy chin and big mouth.
