Frog!!

There was a frog in our pond-in-a-bucket and we watched him for quite a long time. We put a piece of slate for him to climb out over - but he ignored it! Eventually, by an almighty effort he jumped out and descended into the nearby flower bed and soon made his escape!! He was only about 3ins long - 5ins when he jumped! - but we have no idea where he came from! We wonder if he will ever return!!
