The premise (which should spawn some discussion about internet and email safety with parents whose kids are old enough) is that Telly, who has sent his friends a request for replies after setting up a new email address, gets a mysterious email message from a friend who asks him to guess who they are. Telly and other Sesame Street friends search high and low to find out who the mystery emailer is! There are a lot of Sesame Street animated clips and songs to help the plot along, including a GREAT bit with Cookie Monster and Prairie Dawn. If you're raising a budding hacker, this is for you!
