Dr. Marbles is captured by Hacker and taken to Castleblanca, a Cyberspace version of Transylvania. Hacker’s 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.
