Snail and the Whale featuring the voices of Cariad Lloyd and Arnold Brown

Created by Oscar-nominated production company Magic Light Pictures and based on Julia Donaldson and Axel Scheffler’s children’s book, The Snail And The Whale is the uplifting story of a tiny snail who longs to see the world, and “manages to hitch a ride on the tail of a huge humpback whale,” according to the synopsis.

Rob Brydon, who has starred in all of Magic Light’s animated specials for BBC1, said: “It’s always so wonderful to work with Magic Light on these animated specials for Christmas. The Snail and the Whale is a longstanding favourite in our house.

“It’s an epic journey across the globe, where the tiniest creature and the mightiest mammal experiences the vastness of our planet together,” he added.
