Wendy takes to the mudbanks in a white shirt, blue denim dungarees, and blue wellington boots.

She wades into the soft mud, sinking past the tops of her wellies till she's sitting in the mud. She crawls about, gettiing more and more coated in clay as she goes, her clean dungarees and gleaming white shirt gradually succumbing to the endless advance of the thick, brown river clay.

She makes her muddy way right to the waters' edge and plays in the sloppy mud there, ensuring her entire outfit is completely drenched in liquid clay, before clambering up the slope, and then sliding back down it again!

As well as over 500 pictures, there are three brief video clips of Wendy slithering about in the mud.

Eventually she sits on the drier mud at the top of the bank, showing off her mud-drenched clothes.
