Rex the Runt: How Dinosaurs Became Extinct

Our plasticine pooch pal Rex welcomes us to his dreamworld.

When Shaun decides to take the day off and have some fun, he gets a little more action than he bargained for. A mix up with the Farmer, a caravan and a very steep hill lead them all to the Big City and it's up to Shaun and the flock to return everyone safely to the green grass of home.

Robbie the Reindeer (voiced by Ardal O'Hanlon) arrives at the North Pole, ready to take his place as navigator on Santa's Christmas sleigh team. However, Robbie is soon plagued by doubt regarding his ability, and sets out to regain his self-respect and the admiration of his team-mates. This festive animated tale also features the voices of Jane Horrocks, Steve Coogan, Caroline Quentin and Harry Enfield, and features a script co-written by 'Blackadder' writer Richard Curtis.

The gang journey to the North Pole, and drill a hole to find out "What's at the center of the Earth?"
