Chilly
From Tardis Wiki, the free Doctor Who reference
Chillys were students of the New World University.
They wore a uniform consisting of a yellow baseball cap bearing the New World University logo and a dark green sweatshirt with the NWU logo in yellow across the front, as well as headphones through which they listened to a hypnotic electronic beat.
They had all been possessed by the Great Intelligence. (HOMEVID: Downtime)
