It's Valentine's Day, and Hacker captures Doctor Marbles and Lady Ada Lovelace, placing them inside a time machine invented by the mathematically-minded Lady Ada. The kids and Digit must decipher a series of poems left behind by Lady L, and free them from the time machine before it time travels to the nether regions of cyberspace -- never to return!

Ahh,""Totally Rad""...this was the Cyberchase Season 2 premiere! At the beginning of the episode,(the)Hacker,voiced as always by Christopher Lloyd,being the evil villain with an oversized ego that he usually is, takes over another cyber site. This time,it's Radopolis,a cybersite dedicated to extreme sports...and to top it all off he declares himself the King! In an effort to ""declarate"" the cybersite's independence,our hero,two heroines and the cyboid Digit LeBoid, challenge the Hacker's extreme team to a winner-take-all skate-off. Matt=Skateboard Jackie:Mountain Bike Inez:Scooter But there's just one catch: high-scoring tricks need as much area as possible and the field keeps mysteriously changing! With Digit LeBoid,voiced greatfully as always by Gilbert Gottfried as the CyberSquad's coach, the kids put on a dazzling display of scooting, boarding, and biking, but can they match their performance to the changing arena? The Big Idea: Different shapes bounded by the same perimeter can en

Hacker infects Motherboard with a new virus -- one that causes her to make cyber-citizens act mean. Digit and the kids go in search of an antidote: 2/5 of the Electro-Root, 2/8 of the Healing Stone, and 1/3 of a box of Hacker's wig gel -- a strange antidote indeed! Will the young cyber-heroes be able to gather the ingredients and figure out how to properly mix these odd fractions before it is too late?

Hacker becomes a good guy! Can this possibly be true? A new, reformed Hacker runs for election against Motherboard, claiming to have done five good deeds, and promising to turn over a new leaf. Can the kids find a counter example that proves Hacker is lying -- or will he be elected the new ruler of cyberspace? Guest voice: Al Roker as ""Sam Vander Rom."" The Big Idea: When people use words like always, never, all, or none to claim something is true, be suspicious! Such claims are often false, and you need only a single counter example to disprove them.

Motherboard mistakenly sends a treasure map to Hacker. The treasure is the secret to the legendary cyber-pirate Ivanka the Invincible's invincibility. If Hacker finds it, cyberspace is doomed! To help Motherboard, the kids must find the secret treasure before Hacker does, and use their skill with angles to read the strange map that contains only riddles about twists and turns. The Big Idea: To turn something so it points in just the right direction, use an angle to measure the size of the turn.

For Mother's Day the kids must deliver flowers called Madres Bonitas to Dezi, a decimal lover.

Binky must get help from Digit & the kids to get back the Eye Of Rom from Hacker's icky hands before the Mummy wakes up in exchange to tell the gang where the Encryptor Chip.

The kids are enjoying a day in R-Fair City, where Glowla, along with her giant whale partner, Spout, are performing. Suddenly, Spout starts rampaging through R-Fair, and Glowla is captured! No doubt it's all Hacker's doing.

Buzz & Delete kidnap Master Pi, but the leader gets his revenge by doubling the treasure he gave them to too much to handle, while Digit & the kids try to get the Good Vibration from Hacker.

Hacker poses as a virus exterminator. He fools Ms. Fileshare into entering her lair, the Cybrary, with bogus bar graph comparisons. Hacker releases his bugs, but it's Hacker who pays the price with a bout of amnesia. (He's forced to work for Buzz!) But the bugs are still out in the Cybrary, seizing control of various sections. Ms. Fileshare insists the CyberSquad that, if she is to believe them, they must provide an easy way to compare the number of bugs in each Cybrary section.

It could be the most talked-about wedding in all of Cyberspace: Hacker and the Wicked Witch—claiming to be the long-lost daughter of a powerful king. The real Princess is trapped in a series of mazes.

Digit and the kids are asked to solve a mystery and prove a person innocent of theft, but eyewitnesses say that the accused is guilty.

Hacker, claiming to be born again, visits Motherboard on Halloween begging a full pardon. He brings a mechanical frog to the Motherboard's garden. What no one yet suspects is that this frog is intended to hop over to Motherboard's CPU and destroy it.

Hacker works on a plan to destroy Motherboard, but Buzz and Delete screw it up. So Hacker has to get another one. He goes on this cooking show to win the golden cyberchef award. Can the kids and Digit stop him?
