Maida Vale Sand Creature

With thanks to Nancy for the picture of the mysterious Maida Vale Sand Creature:
“There have been road works outside our office on Clifton Road, Maida Vale, for the last month or so.  They have been coming to the end or their work and re laying the bricks.  Last night they had left a pill of industrial sand, this morning it has been transformed into a giant lizard/dinosaur type creature!”
