Watts of Halloween Trouble (Episode #1101)

PBS Kids: Tue, Oct 31, 2017 -- 7:00 AM

Matt is setting up the farm for his family's annual Halloween Pumpkin Patch Party and he is so excited! All his relatives come for the celebration, and even Grammy will be there this year! Inez and Jackie urge Matt to take a quick break and go into Cyberspace for Haunt-O-Rama at R-Fair City - an amusement park cybersite lit up to the nines for the Halloween holiday. The girls assure Matt he will be back home in plenty of time, and he agrees to go. But all their plans change when Hacker traps the kids on R-Fair City, hacking the portal system so they can't get back to Earth! (He thought he was keeping them out of Cyberspace for good, but alas, Buzz and Delete botched their task yet again.) Upset that he came to R-Fair City in the first place, Matt is worried about missing his family's party. The kids must find enough energy on R-Fair City to power Digit's old Portal Rebooter and fix the system. With the Halloween celebration in full swing, can they find enough big and small ways to save energy amid the bright lights? And will Matt make it back in time to see Grammy?

And what will happen to the kids when they go inside Motherboard to track it down?

A Recipe for Chaos (Episode #1002)

PBS Kids: Mon, Oct 30, 2017 -- 6:30 AM

But if Hacker wins, the kids must leave Cyberspace forever! Who will win the hearts--and stomachs!--of Castleblanca? Big idea: Eat a balanced mix of food at meal times to keep your body healthy. Math concepts: Data Representation/Pie Charts.

Castleblanca (Episode #102)

PBS Kids: Sat, Oct 28, 2017 -- 6:30 AM

(topic: Finding Meaning from Data) - Dr. Marbles is captured by Hacker and taken to Castleblanca, a cyberspace version of Transylvania. Hacker's goal: transfer Marbles' brainpower into his newly-built robot named Megabyte! Summoned by Motherboard, the kids and Digit arrive with the knowledge that Hacker has taken Marbles to a castle - but which one? There are hundreds and hundreds of castles. To find Marbles, the kids must master the art of properly collecting data, organizing it and graphing the results - which are sometimes surprising! The Big Idea: Data is a lot more than a collection of numbers. When you gather it, organize and analyze it, you can discover useful information hidden in the numbers.

Spheres of Fears (Episode #610)

PBS Kids: Fri, Oct 27, 2017 -- 7:00 AM

In his latest and possibly maddest scheme ever, Hacker traps Digit and the kids in one of the dreaded Spheres of Fears, a mini-galaxy of orbs populated by eerie creatures called Creepers. He wants them out of the way so that Delete, in a diva star turn, can impersonate Motherboard and convince everyone in Cyberspace to cause chaos everywhere. No one can stop him now! To unlock the door and escape their Sphere, the kids must find the codebook-which Digit remembers is at the opposite end of the Sphere's diameter. And there is no way any of them will make that creepy journey alone! As chaos builds in cyberspace, the team uses the relationship between circumference and diameter to overcome obstacles, and their fears, in the search for the codebook. But can they find it in time? If they fail, chaos will reign supreme, and Hacker will take over the virtual universe forever!

Codename: Icky (Episode #116)

PBS Kids: Mon, Oct 23, 2017 -- 6:30 AM

(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.

He wants the lot for his new Gollywood Tower, which he claims will broadcast entertainment to all of Cyberspace. (The tower is really meant to corrupt Motherboard's hard drive.) The CyberSquad goes up against Hacker at a city council hearing. Will they get their park, or will Hacker dazzle the council into approving his tower?
