We have a pond in our garden that gets a crazy amount of frog activity. It hits about half 8 at night and over 20 frogs hop out and go hunting bugs in our grass!
More recently our tadpoles have been changing into baby froglets. I got a (bad quality) picture of one the other week. You can see how tiny he is compared to my sister's finger.
Here's the picture - http://bompity.co.uk/files/large_photos/frog.jpg
(It's pretty large!).
