Bit of movement

I'm in the midst of digging out some potatoes when my eyes get distracted by a bit of movement. What's that? A spider? No, there between the bags of growing potatoes is a tiny, perfectly-formed, frog. It's only about the size of my fingernail. Clearly this damp patch, right next to the bog garden, is its home. I go back to my bran-tub hunt potatoes and leave him in peace.
