Snail Trail

A slimey little bugger making it's way across the window.
I would have gone out and flicked it off but for one thing it was raining... and for the other, the small yoghurty handprint (it's either yoghurt or snot??) on the inside of the window is a far greater trail than any snail could make.
Although saying that if one of these was to make it's way across the window it would take a few washes to get rid of it's trail!
