What is it?

Walking in the woods early this evening I spotted this strange formation. Maybe it was the way the fading light caught it but to me it looked like a pair of hares . M thought it looked like a giant snail when I showed him.

What do you think?

Please excuse lack of comments - we are working flat out in preparations for the forthcoming Public Inquiry into Judy Murray's proposed tennis centre etc on our Greenbelt.
Oh yes, and we have got to raise £5,000 to cover our expenses.
