"Shari Spotter and the Cosmic Crumpets"
It’s Starlight Night, the annual holiday when all the stars in Cyberspace are refreshed for the new year. But Hacker concocts a scheme to darken the stars of cyberspace forever. He sends Buzz and Delete to stop all production of the new star circuits and take inventor Archimedes away to the Northern Frontier. With the ceremony only hours away, the kids and Digit must find a simple way to make the complex circuits and rescue Archimedes – all before Hacker turns out the lights in cyberspace!
- The December 31 2010 airing of the episode is the very last Cyberchase episode to air on KCET Los Angeles, California due to the station dropping its affiliation with PBS after 40 years the next morning.
- The girls' suits while they infiltrate the Grim Wreaker reference those from Fortress of Attitude.
- The song at the end is sung from the tune of the Christmas song, Silent Night.
