The kids must collect and organize data to find which castle Hacker is hiding Dr. Marbles in.
(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.
