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?
