with Dr Desmond Morris and Sarah Kennedy
What makes reindeer fly? And robins sing? Who got turtle doves as a present?
Which animal would find a welcome in Fawlty Towers? Brian Blessed introduces his family and other animals. Michael Fish, the weatherman, brings an unexpected pet.
And they are joined by Ken Dodd, Robert Kilroy-Silk, Rick Wakeman, Andrew Sachs, Rustie Lee and a lot of friends. Donner and Blitzen turn up too.
