Plasticine Snail Models

These images are from the Aardman produced tv show 'Creature Comforts. I am hopefully going to make my snails like these eventually but with the added shell. Even though they are made out of plasticine, they still have really good detail in them.

These images were for an advert for The Daily Telegraph about moving house. I am not entirely sure wether the snail is really life-like plasticine or actually real.
