Curious and Curiouser!

Sorry about the image! There is no way to make it look pretty! Mr Lif spotted this frog when out for the evening walk. That white stuff on the legs is ice! The temperature here today has not dipped below 5 degrees so there isn't a logical explanation as to why a frozen frog should be laid out by the side of the burn. I wonder if it was one of those meteorological phenomenons when icy frogs fall from the sky?

Answers on a postcards please :)
