From Will Vinton and co-hosted by Rex (Johnny Counterfit), an erudite Tyrannosaurus rex, and Herb (Tim Conner), a dimwitted and bespectacled Styracosaurus with a gluttonous appetite. Two characters who appeared in previous Will Vinton videos dating back to 1980 including "Dinosaur", but this Christmas special is the first in which they have dialogue and contemporary personalities, vaguely parodying Siskel and Ebert respectively. Situated in a facsimile of London's Christmas Square, Rex and Herb introduce several stand-alone videos of Christmas carols and holiday standards and discuss the origins of each song relating to different holiday traditions around the world.
