Here's the frog but where is the water

Another slimy animal to post about. But this new animal, unlike the snails I wrote about on Friday doesn't leave holes in dad's lettuce or make a horribly unmistakable crunching noise when accidently stood on in the dark. In fact these creatures don't make a great deal of noise. But who am I? A slug? Of course not. A Common Frog. But not any old frog. A frog which was, unusually found no where near water.

We were just clearing the long grass near the fence when a large frog jumped out of the overgrowth onto a low wall nearby. It was clearly aware of our presence and froze there. It stayed there for a while which allowed me to take a few pictures of it. After that, we let it hop away back into the grass. We certainly decided not to cut the long grass any more for the time being.

So the question is, what was actually doing there. Well, we have seen frogs in similar environments in other parts of the garden too. But again, not a pond in sight (although I intend to get one soon). It must have come from a pond or stream but I can't think of anywhere nearby where there is one. I am definately not an expert on frogs and other amphibians, and I still have a lot to learn, but I do know that frogs' eggs are laid in water and float. So where on earth has this one come from?

Maybe it made the dangerous voyage accross the railway line from a pond, or hopped miles from the nearest little stream. I simply didn't know. I thought and thought and thought until every brain cell was worn out. I came up with only one more idea. It could have come from the sewers, or drainpipes somewhere.

Let the pictures make up your mind!
