The dastardly Hacker (Christopher Lloyd) takes over the Radopolis cybersite, declaring himself King in "Totally Rad," the season premiere of CYBERCHASE. In an effort to dethrone him, the kids challenge the Hacker's extreme team to a winner-take-all skate-off. There's just one catch: high-scoring tricks need as much area as possible and the field keeps mysteriously changing! With Digit ( Gilbert Gottfried) as coach, the kids put on a dazzling display of blading, boarding, and biking, but can they match their performance to the changing arena? The Big Idea: Different shapes bounded by the same perimeter can enclose very different areas. Math Topic: Perimeter/Area.
