Castleblanca: Dr. Marbles is captured by Hacker and taken to Castleblanca, a cyberspace version of Transylvania. Hackers goal: transfer Marbles brain power 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, organising it and graphing the results -- results which are sometimes surprising! A Day at the Spa: Hacker finds the Krystal of Kalmoor, the powerful orb that will give him eternal power. By possessing the Krystal, Hacker can roam cyberspace and create havoc without having to recharge his power. When the kids and Digit arrive to retrieve the Krystal, they are stymied by a series of switches, levers and buttons. Faced with the challenge of too many choices, the kids discover the value of lists, tables and, yes, tree diagrams! Return to Sensible Flats: Something is amiss with the bliss of Sensible Flats. The reservoir is dry. The town is out of water. And the folks who live there are leaving as fast as they can. But why? When the kids and Digit arrive, they use line graphs to reveal the true story of what happened - and all lines lead to Hacker, the newest resident of Sensible Flats.
