Freefonix - Season 1 Episode 15 Death of Cool

In an attempt to bring down Freefonix before a big Freewave festival, Nerdry programs a viddy mail virus which causes Freewavers to lose their cool. The virus turns Freez into a nerd and Mo into a 1970s lounge lizard. Only BB, who is too much of a "techophobe" to check her email, is immune. During the concert, BB must get over her fear of technology and figure out how to reverse the virus so that Freez and Mo can get their cool back.
